For my old roller shutters in the apartment, some of the tape holders were broken off at the top or even torn off. I thought of a simple solution to thread the roller shutter tape and ensure easy installation in the wall.

There are two models depending on the extent of the damage caused by the torn-out roller shutter tape holder. Of course, the component must be printed stably in order to withstand the forces of such a roller shutter.

For a smooth roller run, Igus Iglidur i150 is recommended, at least that's what I used. Otherwise, strong walls (4-6) and a stable infill (at least 35%)
