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

This is a simple, yet rugged design, weighing only 6 lbs and with 13x13x14" volume with a 8x8x6" build area. While assembly is pretty simple, the small size and rigidity of the design make shipping assembled printers attractive.

Reason for this BuildA cheap, small, light printer with full size capabilities.
