Calibrating the Cheapskates

You should consider printing the belt tensioning devices on Thingiverse, that will enable you to put tension on whatever side you need it on to keep the belt running straight.

Don't think these will work for a V2 because of the difference in the upper bearing structure. Maybe someone can come up with an alternative solution to adjust the new structure without putting too much of a load on the front where the melamine is thinner.

You are correct. I didn't consider that you had a version 2. I haven't seen the V2 and I haven't seen any tensioners for it yet.
