R/C plane axel wheel retaining collar.

I am building a Slow Stick r/c plane using the 3D printer files designed by a fellow member on here (Qromer) and I needed some retainer collars to keep the wheels on the axle shafts for the landing gear.

The collar is designed for a 4mm diameter axle shaft. Dimensions; 10mm long x 10.1mm OD x 4.2mm ID, with a 3mm hole for the insert. The threaded heat set insert is for a 2mm screw, dimensions are 3mm on the small OD 3.5mm OD on the teeth and 3mm long.

Printed from PLA, 1.6 layer height w/ 50% infill.
