There are 2 models: 20mm wide and 50mm wide. The 20mm one is suitable for household transparent tape, and the 50mm one is suitable for packing tape. You can resize either one as needed for other kinds of tape.
Both are quick prints; PLA or PETG; no supports.
Just put it under the end of a roll of tape so you can find it later.
The author marked this model as their own original creation.
