Filament rack holder shelf made from 16mm tubes

Hi! I spent a long time thinking about how to build a filament shelf for my setup. I looked through a lot of options, but none of them quite fit my needs, so I decided to design my own filament rack.

I initially tested a holder using an M12 threaded rod, but unfortunately, it didn’t have enough rigidity and bent under the weight of the filament. So in the end, I went with 16mm chrome-plated steel tubes — the kind typically used for store shelving. The 1,5mm wall thickness provides great stiffness, and they also look really nice and are quite cheap - around $7,50 for one 300cm piece. EAN 5904259598897. In Europe, it likely won’t be a problem to find the same or similar ones made of aluminum.

I tested the whole setup under load, and at 35 kg the wall plugs ripped out of the wall — but the holder itself remained completely intact.

Now it’s been a year since I installed it, and I haven’t had any unpleasant surprises. Everything is solid and stable.

The wall-mounted part comes in two versions — interlocking or single. You can choose depending on whether you want to hang more than one level.

Everything in my setup was printed in PETG with 4 perimeters/walls and 25% infill.
