These are 3 different models for hanging spanners, from about size 8 up to 27 or so. Bigger spanners need more space in between them, that is why there are 3 different sizes.

This is for IKEA SKADIS board.

I wanted to fit at least 3 spanners ON EACH hook, that is why I made this one, most hangers I see only fit 1, maybe 2 spanners, but I try to keep 3 on hand in my garage (maybe even 4 on the really small ones).

Print it with as much infill as you need for strength, I printed mine in PETG cause it will be in a cold space, but if you use it in warm indoor area, you can probably get away with PLA no problem. I had some issues with lifting on the thin sides, but I think its due to the environment my A1 printer is sitting in, the edges tend to get a bit cooler, even if it lifts up, its mostly a cosmetic issue.

The print file contains 3 plates with one on each, and the last place contains 17-27 size on same place for easier printing.

UPDATE: I modified the larger of the 3 different sizes to be significantly beefier after testing it out.

Enjoy, boost if you feel like its worth it!
