White-board Eraser with magnets

Description

Not exactly a remix, since I didn't use any original files, and it quite drifted from the original design. But it was inspired by it; specifically the way to fix and tight the fabric. The main differences (outside the fact that it was redesigned, which change details, shapes, sizes, ...) are 1. I use only 2 pieces instead of 3 (container is also the retainer. Which works, because the gap with the outside part of the container is bigger than the one with the inside part: when you insert the insert inside the container, the fabric gets tight) 2. I added holes in the container, to ease the separation of container and insert (to change the fabric, for example) 3. I added places to stick 1cm diameter magnets. Instructions: print the 2 parts, without support. if you wish, glue 2 ø1cm magnets in 2 of the holes (there are 4 holes for magnets. But in practical, 2 magnets are enough). wrap the insert around a fabric as large as the insert Plug the insert into the container; that will tighten the fabric start erasing. I provided .scad files, so that you can adjust * overall sizes, called L, W and H in the code) * gaps : e is the gap between insert and the outside part of the container; ee the gap between insert and the inside part. e must be larger than ee. Understand that it is not because of friction which outside part that the 2 pieces stick together, but because friction inside. So e could be 1 inch, if it weren't for esthetics reasons. Whereas ee must be just large enough so that is is possible to assembly it with fabrics stuck between the 2 parts. You may have to increase ee if you use a thicker fabric, or to decrease it if you use, as in the original design, paper tower. On mine, I've used a piece of an old pair of jeans. Thick enough, and unsuitable to make covid masks anyway) * anything else if you feel like altering the code other than initial constants.
