This is version 2.0 of the original dog ball holder I designed a few years ago. This one has a pivot and hinge allowing it to be compliant with the user’s movement making it more comfortable and also more reliable. In addition, I have made it collapsible so that it can be compacted for storage.

100% printed - no hardware, fasteners, or adhesives required. No additional support is required.

How I print it: Material = I recommend PETG but any material should work.
Nozzle = 0.4mm Layer height = 0.2mm Line width = 0.4mm Wall count = 4 (1.6mm) Infill = 40% Ironing = ON (recommended but not critical)
