Clippable Holder for Savic Cages

thingiverse

To prevent my rats from climbing up their cage on the outside, I designed a holder to attach a cardboard outside of the cage doors. The holder can be clipped between the bars (which are about 3 mm in diameter and separated by a space of 13 mm). This prototype is rather small. If the clip should hold larger and heavier object you should probably increase the size and print it with a high infill.
