Sillybutts Breacher Lifter Roller with Bearings (Smoooother Prime)

I noticed the screw threads eating into to OEM Roller. So I designed one with Ball Bearings to minimize friction.

A new version for the “Lifter Roller” with ball bearings. I had the problem that the screw thread had eaten into the lifter roller (see pic), causing a lot of friction and making it very difficult, or even (if I pushed back slowly) impossible to push the prime part back. This new roller ensures very smooth prime action in both directions with the help of two easily obtainable ball bearings.

Two 693ZZ ball bearings 3 mm x 8 mm x 4 mm are used.
