This is a clamp to fasten the label carrier paper in an ENOS bottle labeling machine. The original part broke at its handle and this can replace it fully. See pictures for a comparison of the original and the printed part and for how to use it.

The clamp was constructed using OpenSCAD (.scad file included). Some changes were necessary in comparison to the manufacturer's part:

• The height has been reduced to 180 mm to fit a Prusa Mini's maximum print height.
• The handle has been made wider and flat at the top. This creates the base for the print and also makes it much easier to grab while the part is in use later.

Notes:

I have printed this in PLA as well as PETG. Bot work fine, although with PETG I had to disable the cooling fan for better bonding between the layers. Before that, prints were very brittle and broke easily at the layer boundary. With PLA I experienced no such problems.

This is a very thin and high model to print. Good first layer adhesion is important for it to work. I used the standard smooth steel sheet of the Prusa mini instead of the textured one which would normally be recommended for PETG prints. Adding a Brim for printing might help with that too, but it was not necessary in my case.
