Tape-based fiber tip cleaner

Body for tape-based fiber tip cleaner, compatible with Thorlabs FCC-7021. 

The already-used part of the tape is spooled on a geared wheel, which can rotate only one way, preventing unspooling it. Two sides, A and B, allow using both sides of the tape - however, you may not use the B side until a couple of turns of the geared wheel, such that the inside would clean up first. The side arrows show the direction of moving the fiber tip on the tape.

Hold together with two M4 screws and nuts. No glue required.

The provided gcodes include layer-color change and small organic supports, where necessary. I printed it with 1.5x speed ratio.
