Tape Dispenser for 50 mm (2 Inch) wide Tape

Remix of a really great design.

I changed a few things: This only fits 50mm (2 inch) wide tape rolls. Thus all dimensions are a bit smaller which also helps reducing the printing time. I also changed the attachment of the roll.

To me the most important part to change was the "blade part". Since I know how hard it is to saw and drill into saw blades I wanted this design to work also for packing tape without the need of a metal blade.

I achieved this aim at least partially. Like the original design, this dispenser works best for blue tape and similar less strong tapes. But it also works for packing tape, but not as smoothly as I wanted it to be.

So this is a work in progress. I'm still working on a better solution for packing tape.

Additional parts needed:
6 countersunk bolts M4 x 20mm
6 nuts M4
