Last year the Felix 2.0 was our “surprise hit.” This year’s model, the fully assembled Felix 3.0 (also available as a kit) has been upgraded with injection-molded parts and a dual-extrusion option, but it retains its portability, minimalist feel, and excellent print surfaces.

This machine doesn’t ship with a printed manual, but their site provides a well-
illustrated setup guide and configuration files for KISSlicer and SFACT.

The tiny bed-leveling nuts are hard to access, but we liked the Felix’s two-part leveling and filament management systems.

There were some major issues: Our prints were offsetting/shifting to the side. Felix support said to tighten the belts, but the support forums diagnosis was improperly adjusted, overheating stepper drivers.

Without the proper tools on hand we opted for an active cooling solution. Opening the electronics case and positioning a fan across the stepper drivers enabled us to complete our test prints.

Fix offset prints by adjusting the stepper drivers with a nonconductive screwdriver and multimeter, or use active cooling.
Portability, large print bed, dual-extrusion capability, and continued upgradeability: A Felix 1.0 can be upgraded to a Felix 3.0.
