About this 3D model

I found some other models here but I had problems with all of them. So I had to re-print my old model. You need 5 magnets 6x2mm . As stability junkie I printed with 8 walls. You have to make a stop after 4mm to insert the magnets, I fixed them with a drop of glue. Using the fuzzy walls in the slicer brings a lot of grip. So I also uploaded a .3mf file with a fuzzy wall modifier cube that workes well for me. I originally posted this model at Printables .
