Differences of the remix compared to the original
The original model was a bit too heavy for my setup, especially since I mostly use lighter solder spools (100g to 250g, up to 500g). I decided to reduce the overall size and material usage without losing functionality.
Additionally, I didn't have the 9800 bearings specified in the original design, so I re-modeled the entire assembly from scratch to fit standard 698-2RS / 698ZZ bearings (8mm ID).
While heavily inspired by the original concept — which is by far the best design because the inner spool diameter doesn't matter at all — this is a complete ground-up rebuild.
Key Modifications & Improvements
Weight & Material Savings: Reduced total filament usage from ~75g down to ~43g (including supports).
698ZZ Bearing Compatibility: Re-engineered axle pins (8.05mm) for a snug, precise bearing fit.
Axle Stop Shoulder (Achsbund): Added a shoulder on the pins. This prevents the rollers from shifting axially and ensures force is applied strictly to the bearing's inner race.
Material-Efficient Base: Optimized base plate geometry with a central cutout to maximize weight reduction while maintaining rigidity.
Recommended Print Settings
Material: PLA (PLA+ not required)
Perimeters: 3 (essential for pin strength and shear resistance)
Infill: 15% Gyroid
Supports: Organic / Tree Supports (Build plate only, 0.2mm Z-distance)
Layer Height: 0.20mm
Note: Supports are only required for the overhang underneath the roller flanges and detach very easily.
