- I have exported two sizes but the design is parametric so you can make your own version (d_clip is the only parameter you have to adjust) - to achieve maximum stiffness print the clips with 5 perimeters (using a 0.4 mm nozzle). - there is a ~ 15 mm long brigding in the model but no support needed at all - most printers should handle this fine - I have tested the model with PLA, ABS and PETG
