Added a rotating cylinder as a separate print profile if you want to use the filament spool holder to feed your printer directly from the holder

Added a very simple Dry box for those who don't want their filaments exposed:

Do you, like me, have an unreasonable number of open filament spools?
I wanted to create a solution that takes up little space but holds many spools and is easy to manage.
So we build vertically!
A 180cm wooden dowel with a 28mm diameter (purchased at Jula) acts as the frame.
Each arm has a printed ball bearing which makes it easy to pull out the spool to be used.

Printed in PETG.

Wall mounts are screwed onto the wall and secured with 2 screws.
One mount at the top, one in the middle, and one at the bottom.
The corresponding mount is threaded onto the wooden shaft and pushed into the wall mount where it is locked with 2 M4 x 30mm screws and nuts for each mount (Total 6 M4x30mm).

Mounting of arm for filament spool holder:

The arm is threaded onto the shaft with a spacer on each side, the spacers are clamped against the arm on each side and screwed fast with small wood screws (4 per arm) I have used ST M3x10mm leftover from LED kit 001. For me, 78 small wood screws were used for 18 filament spools.
Make sure not to leave any gap between the arm and the spacer as the arms will then hang awkwardly.

The threaded pin is screwed into the arm on the desired side, it's easiest if the round sleeve is mounted first so no tools are needed. The threads are quite tight so be careful to insert the thread straight.

Theoretically, you can also hang this horizontally but the wall mounts are designed for vertical mounting.

I take no responsibility for any property damage.
Think rationally, secure well!
Do not overload.
 

This holder is primarily intended for temporary storage of already opened spools.
