Filament Roller without Bearings – Sturdy & Simple Design

This filament roller offers a robust and minimalistic design, eliminating the need for bearings while maintaining smooth functionality. It consists of:

• 2x Triangles (main frame, M3 inserts for assembly)
• 1x Shaft (central axis, M3 inserts)
• 2x Struts (support beams)
• 4x TPU Feet (anti-slip and vibration dampening)

The design is ideal for printing in PETG or PLA CF for the structural components, while the feet benefit from flexible TPU. Simple assembly requires only 6x M3 inserts, providing a secure and reliable setup.

Printing Instructions

• No supports needed for any part.
• Use 4 wall lines for the shaft to ensure rigidity.
• Infill: 20–30% recommended for triangles and struts.
• Print feet in TPU for optimal grip and vibration absorption.
• Layer height: 0.2 mm for a good balance of speed and quality.

This filament roller is perfect for compact setups and DIY enthusiasts looking for a bearing-free spool holder.
