My wife wanted a spool holder for knitting because she was not satisfied with the trays she often used.
For this reason, I designed this holder. Thanks to the built-in ball bearing, the wool/yarn can be unrolled super easily and silently.
The holder consists of a total of 5 parts, 3 of which have to be printed in any case.
The ball bearing and the M8x30 screw can also be printed, although I would prefer to use metal parts due to the weight alone.
For the rod, I would recommend a 10 - 15 mm wide brim and possibly supports for the holes in the bottom of the base. Otherwise, no supports are needed.
Since I wanted the print to be as smooth and stable as possible, I printed everything with 0.16 mm layer height, 3 walls and 15% infill. But 0.2 mm layer height is absolutely sufficient.

Info:
All lengths of the rod can be combined with any version!

Both the ball bearing and the M8 screw can of course also be printed.
There are many models here on Makerworld that would be suitable for this. (!!! Not tested - only as an example !!! https://makerworld.com/en/models/378392 / https://makerworld.com/en/models/473167)
I would be very happy to receive Makes with completely printed parts - I'm curious to see how well it works. But maybe I'll also test it myself :)
I opted for purchased components because of the weight (more weight = better stability) and the possible running noise.
The ball bearing and the metal screw weigh a good 25 g together. That provides a lot of stability.

Have fun reprinting.
And always remember: happy wife, happy life xD
