Roller Blade Wheel Caster Holder

I didn't like the original restrictive wheels that came with my son's baby walker so I decided to upgrade them. The front wheels holder had to be a little customized, smaller and angled, to be able to use the existing screw holes and connectors. The rear wheel connectors are attached with regular screws and could be used with anything.

It should be printed with the flat part on the print bed, which is inverse from the stl.

I provided the Fusion file so it can be tweaked if needed.
