3mm Extruder for Makergear M2
thingiverse
The Makergear M2's extruder isn't supplied with, nor does it ship with, a 3mm version. To rectify this, I redrew the extruder in CAD and modified it for 3mm filament use. New to 3D printing, I'm still getting accustomed to my first printer; most of my issues lie within slic3r settings. Despite building support into my designs, prints with complex support have been subpar so far. If desired, I can work on a no-support version and upload it. To date, I've printed about 750 grams without any significant problems, although slight bulging in the corners of cubes suggests adjustment to settings is necessary. An update: the V2 file offers larger clearances on bolt holes and stepper inset. Support should be enabled for printing this version. If you prefer a built-in support version, leave a comment and I'll work on it. A few things to note when embarking on this project include replacing the supplied guide tube with a 6mm OD x 4mm ID PTFE tube due to size limitations, using a 3mm hot end from Makergear, and re-determining Z-offset for the new head. When I printed, high temperatures caused bed adhesion issues, resulting in slightly small holes that required drilling. If you experience similarly tight holes, I can modify the design for more clearance. For my print without support, I opted for 100% infill. The hot end slot is intentionally tight to securely hold the hot end; clean out any excess plastic and press it firmly in place using pliers with protective padding. A 625 bearing and 5x18mm bolt work, while a 4x16mm clamp bolt is needed. Use existing bolts for the stepper during assembly.
