For my workshop I designed a wall mounted filament shelf that can be extended as much as you like. For this there are three models:
You need at least the two end pieces and as much middle pieces as you like. For my 2m shelf I used one middle piece.
In addition to the 3D printed parts you need 2x16mm rods or tubes, I used four one meter aluminium rods.
If you like you can open up the holes in any 3D modeling software as I left enough material around the holes. If you have any specific request for sizes, just drop me a comment and I will upload them.
It is a very easy print as there are no fancy geometries if you print it laid down.
I printed it in ABS, but as it is a quite rigid model PLA should work fine as well.
