I had a TON of 690zz ball bearings, unfortunately almost every model out there is using 608zz so I had to do it myself.
The author remixed this model.
Differences of the remix compared to the original
- Using 690zz ball bearings instead of the original 608zz.
- Using heat set inserts to connect the 2 halves together.
- Adding 2 holes at the bottom for mounting using M3x12 screws.
