Thanks to Victor for the great Solder Scroll.
In the original the drive rollers have different diameters, but the gears give them the same speed. This causes a drive wheel to slip. I removed the gears, widened the rollers and inserted a 5x11x5 (685 ZZ) bearing into the small roller. This works very well. LH is the left-handed version (like original), RH is the right-handed version. Use all remaining parts from the original and possibly the Modified spool for Solder Scroll from Jindrich.
I recommend printing out the bearing bolt solidly, using PETG (PLA permanently deforms under load, PETG springs back) and adding more walls.
To test, you can use the small roller with a 5 mm hole (without bearings), then you can try out the difference...
