This one prints up without supports and the mounting magnet is optional. The plastic cutter works ok, but making one out of brass or aluminum might be better.
The magnet cutout is for a 12mm round magnet of any depth from 2-12mm. I used a 3mm deep x 12mm round, glued in after printing.
ProTip: Paint a swatch of super glue on the round part of the cutter where the tape meets it to provide a better surface area for the tape to stick to. Scotch tape does not stick to PLA very well, but it will stick very well to the cured super glue.
Update - there two new versions of the main body that have the cutting teeth built-in to the print - no need to print the separate cutter. Look for the file tapeDispenserBodyMinimalist02.stl for coarse cut (6 teeth) and tapeDispenserBodyMinimalist03.stl for fine cut (twelve teeth).
