Ultimaker internal axle end

thingiverse

This accessory replaces the wooden end of your Ultimaker, fitting inside the body for enhanced convenience. It allows simple attachment of two M3 nuts, eliminating the need for twizzers or nut holders during assembly. The central hole is slightly wider to reduce friction on bearings. Combine with thing 54075 for external use. Print with 0.8mm walls and 20% infill; pushing in the M3 nuts may be challenging due to tight fit.
