The author recommended buying a Lego wheel for this purpose. Link was useless, so designed and printed these.
Modified the basic design, added a hollow cylinder, combined using NetFabb 2023, and uploaded the STL file to PrusaSlicer.
Printed with NinjaFlex TPU on the MK4 with 20%infill, 0.4 nozzle, 4 perimeters.
If you use a different filament, you may have to enlarge slightly to get the wheel to fit.
With a little encouragement, it slid right into place. Works great and very quiet.
ADDED A HALF INCH STRIP 60 GRIT SANDPAPERT ON EACH SIDE TO ENSURE THE WHEELS GRIPPED AND WENT UP THE INCLINE. Attached the the sandpaper with scrap book dots, but most two sided adhesive should work!
