Buffer Wheel for 624 bearing for Core One MMU3 Community, STEP file provided

For me it's easier to resource 624 type bearings as I have them on stock. Additionally I prefer to have a more defined position of the bearing and a washer between the bearing and the door body, to enable free spin.

since M4 is used, a flat headed screw is necessary to make it fit in the buffer area. Additionally it is necessary to drill the mounting hole in the door body to 3,3-3,5 mm.

Needed (for each):

• 1x 624 bearing
• 1x M4x10 screw with flat head
• 1x M4 washer

Be sure to push in the bearing deep enough. It should be as far in as the picture shows, use the bottom chamfer as orientation, then add a standard M4 washer.

If you need to modify it for a different type of bearing or if the fitting is to tight, the step file is provided as well for modification.
