Update 4/20/22: Tweaked the end plates to reduce potential cracking and increase step clearance
# Non-printed parts
- 13 M3x12mm bolts
- 12 M3 nuts
# Printed parts
Print 64 chain links, 32 steps, and 2 end plates. Print 1 of each of the other parts.
It is critical that your printer is well-calibrated precisely leveled before printing these parts. The steps in particular are very sensitive to bed leveling/adhesion. You'll want the first layer to squish only as much as is required to prevent warping; any overextrusion or elephant's foot will prevent the steps from running smoothly. I recommend applying some elephant foot compensation in your slicer to make sure the first layer is the same width as the others.
## Assembly
This is pretty tricky. I assembled in the following order:
1. Starting with the right side, lay the right outer guide down onto your work surface.
2. Secure the right track guide to the right outer guide with 2 bolts and nuts.
3. Place the right handrail mid guide on top of the right outer guide. The right track guide should be in the middle, so that they form a double path for the steps to ride on. At this point I attached the handrail guide to the outer guide by bolting each of the 4…
