Work in progress - X carriage and belt attachments still need to be designed

Tiny purpose-built 3d printer.

Goals:

• Extremely cheap, probably around 40 euro (not including power supply) with 28byj48 extruder, still below 50 euro with Nema 17.
• High quality using MK4duo's backlash compensation
• 50 x 50 x 150 mm build envelope
• Extremely compact < 150 x 100 x 220mm ?
• Easy assembly

Uses 28byj48 steppers, which means this will be a SLOW machine (around 12mm/s?)

Once this machine is done, I hope to make another, better design from scratch as some design choices could have been better.

'Remix' files:

• Modified stepper model included
• Hybrid PTFE bushing listed just because that's where I got the idea for the integrated bushings - see that page for assembly
• Lazy editing of parametric pulley library
