Gridfinity baseplate to hang to a Kupper (Küpper/Kuepper) pegboard (UE/EU/DE pegboard). Printed in PLA, it needs brim or adhesion disks under the pins (already present in the .3mf file).
If you like it or you're having problems with it, please let me know in the comments. It's my second “design” so I'm still learning and I want to improve. Thank you!
The author remixed this model.
