Modular Stackable Filament Rack (20 mm Wooden Poles)

A simple, stackable filament spool holder that uses 20 mm wooden poles.

• 40 cm horizontal poles (can fit 5–6 spools per level)

• 30 cm vertical poles (to save space and allow adding more segments)

I recommend printing at 98% scale for a nice press-fit assembly; otherwise, you’ll need to glue the wood into the segments.

I also made a simple geometric shape inset for aesthetic purposes.

I’ve added a simple clip-on extension for empty refill spools so they don’t take up space on the rack itself (since I had spare 30 cm poles).

I recommend using all four 40 cm pieces for the base level for better stability.  Two long pieces should be fine on higher lvls.

If you’re planning on moving or tossing it around, I highly advise using glue.

Assemble the longer pieces first, then stack it vertically — it gets annoying if you do it the other way around.

Planning to add tags in the future so it’s easier to see what material you have and where.

Also planning an iteration that allows it to be mounted on a wall (because it would look cool, especially with underglow).
