Rep Rack Alcove Filament Storage

I made my model using the same conduit spacing as the RepRack original, adapting it for European standard 20mm (external diameter) conduit. As I was only installed a short span I used PVC conduit, though you may prefer to use metal if you need a longer run. Print two brackets per span and fix it to the wall with countersunk screws. Cut conduit to length and drop it in. Rene's test file here is great if you want to test the same tolerance as my model. I printed with 3 perimeters and 20% infill in PLA and hand no issues. Be aware as quite a long narrow printing you can run into issues with corners warping.
