The support bars of the Gaupen trailer (Norwegian) slides on top of the sides of the trailer. This is somewhat irritating when adding/removing the tarpaulin cover. These clamps fixes this problem.
The design is not super tough as they are made to be low profile. Some care should be taken when slicing/printing to ensure enough strength.
The examples are printed using PETG.
The author marked this model as their own original creation. Imported from Thingiverse.
