It is a very simple model. It has a lip on one side for the bearing to rest against. Maybe you have to very slightly shim around the bearing, as I designed it for a slightly loose fit (at least for my setup).
The screws might be a little weakspot, so watch out not to spilt the layers.
I printed it in Prusament PETG with 4 perimeters, 0,2mm layer height.
The author marked this model as their own original creation.
