I saw a bunch of others models out there, but most seem to require screws (which I don't love in the bathroom and can't do in a rental property) so I wanted something that would fit on my build plate (Prusa Mk3) and would be supported by 3m command strips (or the aliexpress knockoffs that I'm using) so can be easily removed or repositioned as needed.
This model fits perfectly on my build plate and is secure enough to hold 3-4 rolls with plenty of margin. I think it looks pretty good as well.
Infill % doesn't really matter as the entire thing is basically just walls.
The author remixed this model.
