8mm id air soft bearings

thingiverse

I needed some 608 bearings for a light-duty job in a hurry and couldn't find any pre-existing designs, so I through this together. It uses 7 air soft BBs. 5 of them can easily be placed in the race. Then the last two can be snapped in at the provided gap. Note that it is exceedingly weak on its own but will be stronger when supported by mounting it. Still it is only useful for slow and lightly loaded applications like 3D printer spool mounts. There isn't much clearance, so it will require a well calibrated printer. I also included a 30mm OD version for custom applications, which is stronger and has a bit more clearance. The design is available on [onshape](https://cad.onshape.com/documents/b5abcb50601dad0a506b8317/w/8fa46977a33e8459f720b91b/e/2c983bf8a19b7ac12bc0c78e?renderMode=0&uiState=61c10a3ba2ebdc7a5dd65e5d).
