Monolithic Platform for E3Dv6 Hot End

Sorry I have been slacking..... here you gohttps://drive.google.com/file/d/0B8A_iz ... sp=sharing that's 10mm shorter...... should definately give you enough room to mount your led

Yea, just FYI. Downloaded the STL and it's missing the 3 holes for the rods.

Sorry bout that, all fixed.... Must have had them suppressed when i exported the .stl..... Link is updated with new revision.

love the design and thought id mod it for possible pla use I thickend the base wall to add tubes to it (but I couldn't get the tube generated to work for me) I also added a layer fan mount
I have not yet tested the fitments yet, any help would much appreciated
oh this is also my first mod to

So I have some time to waste at work this week, as I just turned in my last prototype project and they need time to test it . So while they try and see how hard it will be to destroy 2 months of my hard work, I might as well offer up some solidworks skills to you guys. As I already have a working, proved-out model(at least by me) of the mount in a couple different sizes/configurations, might as well start here. I will start with my interpretation of what predawnsky was trying to do. I do not really see a reason to thicken things, but do like the idea of a integrated layer fan for those of you who insist on using pla, and i might try to use it with abs on small features that tend to melt with high print speed. Let me know what kind of features you would like added or dimensions changed. Having done design work for various people with napkin drawings in the past, there are some things that will make this process easier.

Drawings ALWAYS help. If you can show me what you want instead of explaining it, DO IT!
There is a million different ways to model something. If you have a design in mind or want something placed in a particular corner or spot, you have to let me know otherwise I will put it wherever it pleases me and might not please you or even work the way you intended.

I have my old layer fan that came with the kit, and will take my fan dimensions from that. Post results when I'm done.

P.S. I'm sure if i do a search I can find 'em but does anyone have e3d modeled in a better format for solidworks than .stl? A step or iges file would be perfect.

So here is my first attempt. Problem i foresee already is not directing the air enough or at a steep enough angle to keep it from blowing large volumes on the heater block, but hey you gotta start somewhere. Now that you guys have a general idea as to what I am doing, feel free to chime in with your ideas.

I am going to beef up the bottom lip of the fan port to make sure it wont crack when fan is installed(meant to be a tight fit only .003in of clearance), and move the port opening so I can have the volute face at a steeper angle towards the nozzle to keep as much air flow away from the heater block as possible.

Another problem being I cannot extend past the bottom of the platform without having to generate more support than i would like, I am toying with the idea of making the volute/duct as a seperate piece that would press fit onto/into a lip on the I.D. to direct airflow. Any ideas as far as shape/ direction/ size? Anyone tried those fancy rings people print to blow around the nozzle?

Blast! You bet me to the layer fan concept. I'm working on one that will use a regular fan. I'm trying to make mine smaller and more printable with less support material. Hopefully done by this weekend.

Are you planning on using the stock hot-end fan and bracket on yours? I haven't spent a whole lot of time on it, but i don't really see an easy way to make it much smaller without redesigning the pc bracket.

Now that you mention eliminating support material, gets me to thinking that you could fill 1 if not 2 of the voids above the spindles at a printable angle eliminating some overhang and thus the need for support? You could even use that as a mount surface on the O.D. and integrate the duct.

Let me get something rough together to show you concept.

HEY! Stop stealing my ideas!

I drafted the wall in 5 degrees to reduce the top area. Make sure you have enough room to still get the hot end in. It going to require a little more modeling work. The layer fan, I'm thinking about making removable. 30-40mm fan. I'll post my idea soon, maybe tonight when I get home.

I had something more like this in mind..... 30deg draft to straight wall.... if you look close i still have room to make it a little bigger.

BUT, slicing the model a couple times tells me that without a very low fill rate like 5% or so, I am not seeing big differences in print time. Maybe that's just my settings though. As far as mounting a regular fan I think that the new vertical O.D. wall will make things alot easier. If you want I can post this as a step or iges for you guys.

I need to download a model of the hotend, I haven't done that yet. But I was talking about the walls that already there, just tilt them in 5 degrees. I tried going up to 10 degrees, but I think was to much. I have another idea after this one. But I'm going to wait on the reveal.

Awwwww come on...... don't you wanna give me a hint so I can beat you to it?

Attached is the e3d model I've been using for test fit. I'm gonna tilt the walls and see what happens? Curious if there's any real considerable time saving to be had vs generating support, couple of min here and there don't really make a difference unless your talking about making production quantities. But I might be wrong. Plus its always nice to help out the new guys who don't have support quite figured out.

[predawnsky]

nice looking design the reason I mad the base thick was to integrate tubes hidden in the unit to blow on the layers like the rostock air layer fan but using the original layer fan

[BONE]

Thanks for uploading that model of the hotend, I still need to upgrade to 2014 to use it thou. I just tried, but I think I missed the window, need to contact Solidworks about that.

I got some upgrades to trick out the entire hot end setup. It's going to be awesome. If I do it right. That's the trick.

Adding radii at the transition at the top helps reduce the need for support material under the top section also.

You can see the 5 degree angle on the right side.

what software from Solidworks do you guys use

what software from Solidworks do you guys use

Solidworks is the software, it's made by Dassault Systems. It's a pretty complicated engineering and design platform, and thus is pretty expensive. You do have a couple of options if you really want it. I don't know if they still do or not but Solidworks used to have an educational version(at least when I went to school a couple years ago). It's not the full blown software, but its free and you probably will never use most of the locked features anyway. Then of course there is the second option of **COUGH**piratebay**COUGH**. Either way as long as you don't try to make money off of the software and just putz around you'll be ok. Btw the tutorials that are built in to Sw are an excellent way to get started if you haven't used it before.


BONE: I made us switch to 2014 after using a friends laptop over one weekend and noticing new end constraints. Makes things a lot easier in my opinion. It won't let me attach a iges so here is a link https://drive.google.com/file/d/0B8A_iz ... sp=sharing
Btw, your model looks sweet. I get how you managed to get it smaller now. I don't know if the hot end cooling fan still fits with a draft I'll model the fan for reference and see if it will fit. I have print time to just under 2 hrs right now with .3 layers and high infill, but I wanna play around some more and see if i can get one printed today to test.

[BONE]

Yea, I had the upgrade disc laying around, but I think I had to do it by the end of October. Now I have to call and ask them for a new code and so on. Hope it's not a pain.

Thanks. The fan should fit through one of the opening and snap on to the hotend. The opening is still the same size with the drafts. The fan housing is offset, so you need to watch out for that. A fan housing could be built into the platform. But that could cause issues with heat transfer into the platform. I need to quit my day job and work on this stuff full time.

So Just got done stealing all your good ideas. 5 degree rubbed ever so slightly for me in the assembly so I backed it off to 3.5, and it clears just barely(will be fun trying to get it together. I also put the cable management port back because...... well just because. Going to make this one with a very basic layer fan just to see if it works and how well. Probably make one without it too just in case i don't like it.

I clearanced where the fins of the hotend pass by when installing. You can see that in the more first screenshot, look on the inside to the right. I also shorten the distance of the slot to move the installation hole close to the center. I made the walls going up 6mm thick to try and stiffen it up some more. Does it really? Maybe.

I treat all my parts like racecar parts. Do I really need material there and where can I add it make it stronger, stiffer, etc...

Ahhh... yea I never noticed the relief you put in, that is where I had mine rubbing. I'm printing v1.0 now to see what I like and what I wanna change. I might go back to 5 deg and add a relief like yours but I'm not sure because I get a smidge more room for the cable management port. Should be done in about an hour so I'll have time to assemble and take pics before I go home.

[BONE]

I basically got rid of the cable ports and going to bring the wires out on of the openings. I see one open for the hotend fan, one for the layer fan and the other for wire and cable management.

I just had a flash of genius also, I'll see if it works out.

I'm actually pretty happy with how it came out. A little rough around the edges but I printed this one with speed over quality in mind-75mm/s print 44mm/s shell and infill. VERY little support to remove compared to the previous one(but that was the point wasn't it?). Fan fit in fairly easily and the vent is actually sturdier then i thought it would be...... Now to let the hot end cool so i can test fit.

Hey Mike,
That looks pretty good. I'm going to try and post mine again tonight. Can you save your hotend as a 2013 SW file and upload it here? I would like to use it this weekend.

[eatoutmikey]

So it does need a bit of work. As is the layer fan blows directly on the heater block . The hot end fan did fit but just barely. I'm going to extend it by a couple mm to get the bottom of the platform closer to the end of the fan. Btw we are missing the easiest cable management solution..... I stole your idea to use a pin to hold the collar in place so when everything is installed there is that perfectly nice unused space left begging to have wire run through it. Well looks like V2.0 will be printed on monday.

Nope I can't save for 2013, but i did post a link to my google drive earliuer with an iges file you can import.
