Peristaltic pump tube holder for aquarium dosing. Fits up to 4 tubes of 5mm diameter, and fits aquarium glass that is 5mm thick. Move the transparent box upwards in Bambu Studio to scale the height of the model from 1-4 tubes. The default print profile will print a 1-tube holder.

If you need it to be wider for thicker glass, do a cut in the middle and then boolean combine the two cut parts together with a scaled cube.
