SimplrBot

After watching various cantilever type builds here at Openbuilds, I decided to build one. Many thanks to @Indieflow and @Sonny Lowe for sharing their designs and conversations!

I'm not sure if I want to call this a "SimplrBot" (because it's better than a PrintrBot Simple) or a "PrintAir" just because the name is catchy and "looks right" for the design.

I started this in my head just a week ago, envisioning a 6"x 6" build area. But once I had that pretty much built I changed to a 8"x 8". Originally I was also going to use 3"x 3" x 1/8" aluminum plates for the front and rear Z wheels plates. But once I printed some with PLA I've decided that these are strong enough. The main concept that got me working on it was using a 20x60mm extrusion for the frame piece. That height allows a substantial connection joint between the frame piece and the Z extrusion upright (for rigidity) while offering room to mount a PSU and controller board under the bed.

I'm using a MKS Gen 1.4 controller. I also have a MKS TFT32 Touch Pad enroute from China to add to the front Y axis foot.

I'm bolting pieces together (and of course reprinting each multiple tweaks) this weekend. I hope to have a running beta by Tuesday.

The main 2 things I like about this cantilever design are:
1) easy to assemble - quick too
2) $260 Bill Of Materials
