I designed this in FreeCAD. For structure and linear motion I used MakeBlock (blue parts) and a friends CNC machine (naked aluminum). The hot end is the B3 Innovations PICO. The heated bed is SeeMeCNC and the extruder is the EZStruder from SeeMeCNC.
Well, let me know what you think!

Thank you! It took a few months to design and build! I'm thankful for forums like these, so much advice and encouragement! I'd love to share more if anyone has specific questions.

I saw some people wrapping their kits in plastic. I'm sure this works great, but the sexy factor just isn't there for me. I bought "Lexan Sheet - Polycarbonate - .060" - 1/16" Thick, Clear, 24" x 24" Nominal" from Amazon. They also sell a cutter for it... 3-5 passes on the polycarbonate against a straight edge makes for a easy snap.
This is fairly inexpensive (compared to the overall cost), and looks pretty sexy (imho).

Yah... I noticed =(
But I'm a novice YouTubber and I edited that video in PowerPoint, LOL... took like 3 hours... so unfortunately I couldn't fix the mistake. But good point, I can at least fix the description!
