These 3D printed rollers are printed using the highest technology printers available - much better than conventional 'hobby' 3D printers can achieve. Absolutely beautiful resolution, solid nylon impregnated with glass beads for maximum durability. Nylon is a much more durable material than PETG, which other manufacturers use.
These roller (idler) wheels are for the Autohelm 4000 and ST4000. They are compatible with the Black MK1 version of the wheel pilot (not the Grey Mk2 version). They have been redesigned to be much stronger than the original. They are 3D printed in ultra high resolution nylon plastic.
Autohelm manufactured 2 different types of rollers. Early versions had ‘spokes’ on the underside and were quite weak. The later versions had a cone shaped roller - exactly like these replacements. The 2 types of rollers were identical in size and are interchangeable, just a slightly different design.
The autopilot wheel unit contains a total of 7 of these roller wheels.
