I designed a wall mount and storage solution for my lint roller, and printed it in Bambu PLA CF.

You load the .stl file into your slicer and then you separate it into the different 3 objects, and place them as shown on your build plate. You only need support for the four pins on the side of the holder itself, for that i recommend the tree support(place it manually). Otherwise you can just use the .3mf file i uploaded, in which i placed everything correctly and painted the supports.

Use whatever material as you like (except for PETG/PET or PP, because then the glue won't stick properly).

For assembly, position and level the mounting plate as you like, mark the holes, drill the holes and mount it on the wall, using 4x 3.5mm countersunk screws. Then glue the holder and the roll storage together and slide it onto the wall mounting plate.

I recommend 3 bottom- and top layers and 3 perimeters and 20-30% infill. For the wall mounting plate use 100% infill!
