Mini Inkle Loom - Double Frame and Wide Body Remix

As other users commented, the original could not hold any tension, especially with cotton fibers. I went ahead and modified it so it has a full frame that prevents frame flex. While I was in there, I made it a bit wider since torque was less of a concern, so 100mm m4 screws are now required through the body instead of the m4x45 screws. I also corrected a few wonky nut retainers, and repaired all errors that the original files generated when sliced in PrusaSlicer 2.3.0 alpha4. I strongly recommend using knurled thumb nuts, or at the least, wing nuts, to secure the right side frame since it will need to be removed every time the loom is warped.
