H-Tiny 3D printer

Small (150x100) build volume 3D printer based on H-BOT Principle Bed springs and screws are sold as Ultimaker 2 parts on Aliexpress Belt is 9mm GT2 Each idler consists of a pair of F695 bearings with a 695 in between. There's also a 8x5x1 spacer above them for the gantry idlers and two spacers for each of the corner idlers. Leadscrew is a TR8. Bearings are LMK12LUU, 12mm shafts and SK12 aluminum shaft holders Plates are to be made out of either 4.7 or 3/16" aluminum plates. Linear rails are Hiwin 150mm MGN12H for Y axis and 200mm MGN12C for X axis. The X carriage takes an aluminum GT2 belt clamp (bought from Aliexpress). It's made in more than one part so that a different hotend mount can be made for a E3D Chimera or Cyclops in the future. This is a very simple project. It's a bit on the expensive side due to the Hiwin rails, but with a different X Carriage back and idler holders it can be turned into a CoreXY, which would be better suited for larger build volumes and for cheaper hiwin knock off rails. It has no auto-leveling sensor, just use Marlin's manual bed leveling and it works perfectly.
