I finally wanted to try the clear resin (or 'maker juice' as it is called in the Makerworld...;-) on the Formlabs Form 1 printer. So I sat there one recent night and designed a faithful reproduction of a MMC cartridge protector. Seems whenever one comes across a cartridge the protector is lost. I have several MMC cartridges around the house, but only one protector. Now it seems this problem has been solved. Here are a few pics of the finished part. I guess, "transparent" is a matter of definition, and the 3D printed 'clear' material still seems to have a bit of a problem with it. But on the other hand, the outcome really was not too bad. Definitely usable, and definitely much better than a broken off cantilever! Here we go:
The small details like the two protrusions that clamp the protector to the cartridge (below the "UP" lettering) are quite correct in their dimensions and the cartridge clamps in nicely, however with bit less 'grip' than into the original protector. This is a result of the softer material quality of the printed plastic. I could probably increase the wall thickness a bit (or just be happy with the way it is!..;-):
