Filament Guide - V-Slot

As part of my under-desk IKEA Samla mount design, I needed a way to better manage the filament path so that it wasn't scraping against the aluminium extrusions and other things such as the desk itself when printing. So, I designed a simple and small filament guide to fix that. The design could be further simplified to not use bearings but for robustness and longevity's sake, I decided to use bearings.

Print Recommendations

No supports are required for any of the models and all models are correctly oriented for printing.

However, the pin model requires a large brim due to how little surface area its first layer takes up. Don't try it without a brim or it will be knocked over mid-print.

• Nozzle Size: 0.4mm
• Layer Height: 0.2mm
• Perimeters: 3-4
• Infill: Gyroid
• Infill Percentage: 10-20%

Hardware

• 2x 694ZZ or 6942RS bearings (these are the ones I used)
• 2x M4x6mm bolts
• 2x M4 T-Nuts

Instructions

Simply press the bearings into place in the base. Move the roller into position so that it lines up with the inner bores of the bearings and then slide the pin through.
