Ender 3 Filament roller

I made a filament roller for Ender 3. I used for bearings 624ZZ U groove bearings. On one side I used shorter M4 bolts that hold the bearings tightly. On the other side I used longer bolts, because the filament roll width's can be a little different.

2pcs M4 15-18mm bolts for the non movable side.
2pcs M4 30mm bolts I used on the other movable side.
4pcs 624ZZ U shaped groove bearings.
2pcs M5 10mm bolts and M5 washers.
2pcs M5 the stock Ender 3 filament roll holder parts.
