Wire spool
cults3d
My version is intended for 22 AWG cable. I printed all the parts in PLA with 0.5mm layer height. In the image you can see 25[m] of AWG22 cable in each spool, there is a lot of unused volume. Dimensions: Dint = 16[mm] D1 = 27[mm] D2 = 110[mm] H = 50[mm] TotalH = 54[mm] You need 2 "Side" parts and one "Axis", aditionally you may need to make a hole with a drill passing both "Side" and "Axis" parts in order to secure the start of the wire or use super glue. The parts are joined using their built-in thread, with the printing settings that I used (see below) they fit pretty well.
