Summary

There are several other versions of filament roll wall brackets on Thingiverse. I just did my own so it would use 1-1/4" ID PCV pipe that you can find at almost any home improvement store and the rolls do not touch the wall. I designed these with eSUN filament rolls in mind but most other filament rolls should work as well, as long as they are not huge rolls.

Just mount these using screws drilled into where there is a stud in the wall (highly recommended). Cut PVC pipe to fit.

There is a model (center) where the PVC pipe can pass all the way through. It has a hole in each of the PCV mounting holes so you can use a screw directly into the PVC pipe if you prefer that way of mounting it.
