easy to print Customizable Wheel – useful for replacing wagon and grill wheels or whatever you need. The wheel design is intended for easy printing on single extruder printers without requiring support. The tread uses half cones to mimic the traction that is typically achieved with an inexpensive grill, garden cart or push lawn mower The intent of the design is to balance print speed, function and strength taking into account the limitations of inexpensive 3D printers like the Creality Ender 3.

Customizer should work well for wheel from 3”(75mm) to 12”(300mm) and might work for size beyond. Dimensions in the openSCAD file are in mm. It's possible to design wheel

I have printed the grill wheel with my Ender 3 Pro with a .4mm nozzle and the 8.5”(216mm) Wagon wheel With the Ender Pro using a 1mm nozzle, as with any larger print the 1mm nozzle really speeds things up and the heaver lines and walls give a nice strength boost to a print like this.

Tip: it's helpful to under size the axle hole slightly (maybe 0.1mm) then run a drill through it for a cleaner hole.
