There is also a Gridfinity version of the case in the works, which will hold 15 units (9 Gridfinity "units" high or 9x7mm).
Both the cases will be completed after the filter design is posted, since the cases will take some time to print and test. But at least I don't need to wait on parts from China to get them done.
I spent way too long with these simple designs, and probably printed a dozen iterations of the wiper and cutter holder prototypes, before I had a design that I could be happy with. Now I just need to integrate them into the case design, and print those parts to test.
I'm currently running the top of the toolbox first (the part which will have the logo and compartments). I had to print the top using no prime tower, mouse ears only and manual supports along the front where there are some unsupported overhangs, Ideally the model would have no supports. However due to the way the draw latches work, some supports are required. There are also some supports in the area of the case label frame, which I think are unavoidable. I expect that I can print this in 5 almost full plates and 2 multicolor plates (split the multicolor prints to minimize the waste).
