Overview
This guide outlines the assembly and use of an experimental roller side system designed for the 1kg and 3kg variants of the S1+. The goal of this design is to prevent filament rolls from falling off the rollers as material runs low, improving reliability during extended prints.
STL files for the roller sides are available for download via this link. This design is currently under evaluation; if enough positive feedback is received from a wide range of use cases, the roller system will be adopted for production units.

Printing the Sides and Rollers
Recommended Material: PLA+ or stronger filament.
1. Printing the Sides
- Layer Height: 0.20mm - 0.42mm depending on nozzle
- Wall Loops: 2-3
- Infill: 15%
- Supports: none
2. Printing the Rollers
- Layer Height: 0.20mm - 0.42mm depending on nozzle
- Wall Loops: 3-4
- Infill: 15%
- Supports: Default (Add support blocker to shaft hole indicated by red arrow)
3. Printing the Braces
- Quantity: 2
- Layer Height: 0.20mm
- Wall Loops: 2-3
- Infill: 15%
- Supports: none
Assembling a Set of Rollers
1. Press the bearings (624zz bearings) into the 3D Printed Sides
2. Set the 3D Printed Rollers in place on the sides
3. Start screwing in the set screws to act as the roller shaft. All 4 set screws should be started 2-3 threads before screwing any all the way in.
4. Finish screwing in the set screws until they are flush with the edge of the bearings. Ensure they go in straight to prevent any wobble in the rollers during operation.
5. Repeat steps 1-3 for the opposite side. Ensure the rollers are aligned in the opposite direction so that they mirror the first set you assembled.
6. Press in the front and rear braces to connect the two sides.
7. (Optional) Install the rubber feet. These are glued onto the sides when purchased. Removing feet that are glued on may damage them.
Installing the Roller Sides
The Roller sides can be installed using the same method described in this guide.
