Inserts with posts and wheels make tape looping easier. No need to cut the perfect sized loop – just re-route within the insert.
Some of my friends here in Fort Collins set up a lil tape looping workshop at a local theatre. Having done it a few times in the past with varying success and much annoyance, I decided to 3D print little posts to super glue into the case to help with routing the tape. It did not work out as I expected, but sparked an idea that became these 3D printed inserts.
They are made out of PETG, clear or orange, designed and 3D printed by me.
