Floppy disk notcher addon
3D print your own 5 1/4 inch floppy disk notcher add-on.
This is how the C64 cartridge cases turned out. They were printed on Creality LD-002R SLA printer. They look ok to me and the two halves fit perfectly well. Just some attention is needed where the supports were attached.
I have started another print. This time it's C64 cartridge cases. One is for final cart and the other is a "normal" one. Fingers crossed...
