Parametric Tape Dispenser (remix for finger groove)

A remix of jag's tape dispenser, with the finger groove made parametric and wider. In the photo above, the white tape dispenser uses the STL generated by my remix, and the beige is using the original script.This particular STL is designed to fit 1" wide 3M micropore surgical tape. The "travel size" one is designed to fit a half-used roll so it takes less space (eg. in your luggage).I printed mine with PLA and 0.2mm layer height. The threads were a bit rough at first, but warming the nut with a heat gun for 15-20 seconds and putting it off and on a few times (so the warm threads would mush to fit) fixed that problem. You could accomplish the same putting the nut in a warm oven for a moment.Some later ones I printed with PETG were a bit more difficult to get working. Still use the heat gun to help get the threads started, then turn the nut off and on as far as you can repeatedly (might require channellock pliers for grip) until the friction wears the high spots off in globs of junk. Then clean the junk off with a hobby knife.
