Printing:
- 2x spool adapters. Print wide side down; no supports required.
- 2x crossmember flat. Print flat. I created this from scratch as I did not want to deal with trying to print something this tall in vase mode.
- Either:
- 1x Arbor Flat. While this works, the plastic-on-plastic noise is horrendous.
- 1x Arbor Shaft, 2x Arbor Cap. Cap requires support where the screw head goes.
- Print or cut 2x side panels from the original RackStand model.
The sturdier the better.
Materials:
- Required:
- 4x #6x5/8" (16 mm) self-tapping screws, same as used in the rest of the RepRack system.
- Optional:
- 2x M5x30 mm screws
- 2x M5 nuts
- 2x 608 bearing, or printed alternative. I am finding that there is too little friction with metal bearings and the spool ends up over-spinning when it gets to a certain point in its rotation.
Assembly:
- Screw through side panels into crossmembers.
- If using the bearing arbor, insert nut into slot. Bearing goes on cap, and screw goes in from the outside. Thread-locker may be desirable.
I will note that I am using this on a table with the printable wall cleats screwed into the table. I think there is a high likelihood of the spool pulling itself out of the side panels if this is mounted vertically.
