I really enjoyed SzilardA6 Minimalist Filament Storage but I wasn't happy with the Spool Holders: For the 45lSamla box (where the 65l parts fit) I didn't want to use (un)screw nuts every time I have to move something.
As I wanted to start learning OpenSCAD anyway this seemed like an easy enough project.
In the files my learning progress and various versions are included, in case someone wants to "code" review ;)
The holes have a bit wiggleroom to be flexible enough to be moved back and forth without issues.
I'm using two "single sided" parts for the outsides and then as many "double sided" as needed or fit in the box - whichever number is lower. For the Ikea Samla 45l box that came out as four to five double-sided, depending on how wide your average filament spool is. With five double-sided and two single-sided, the box is exactly full with six for the default amazon spools.
The bolt is a quick hack for 20mm threaded passthroughs I still had around (see below).
Parts
8mm (metal) rod in your needed length.
two or four 608ZZ bearings (7mm width, 22mm diameter, 8mm hole).

A cheap plastik box for silica gel
A I2C temperature and humidity sensor for the pi
