Parametric Cotton Reel
by tubular, published
A parametric Cotton Reel constructed by mating two identical halves.
The halves make it easy to retrofit to reprap rods without any disassembly (for a simple filament spool holder).
Also great for cable grommits, eg for closing up a hole in an enclosure or wall after you pass a terminated monitor cable through.

- Adjust the two heights and three diameters at the top of the SCAD file.
- Print two identical half cotton reels
- Mate the two halves together (easier while still warm off the printer). The 3D printer layers help it to all lock nicely.
- If they are too hard to mate, increase the "S" shim value
