1/8th Scale Railroad Wheel Block

thingiverse

This is designed to be a sturdy wheel block for your rolling stock. It's ideal for holding a car in place on the workbench or several cars in line on level ground. To use it, simply hold it on the rail and roll the wheel up onto it. I highly recommend printing this with at least 25% infill since it will withstand some wear and tear. ABS is also a good option, although PLA will do the job just as well. The curved bottom side helps accommodate the rail head for smooth operation. A small hole allows you to attach a long bolt, giving you a more secure grip on the wheel block instead of relying solely on the print itself. I may revisit this design later to incorporate the wheel flange, but it works perfectly for my current needs, so I won't be making any changes right now. You might also consider adding some thin rubber to the underside to improve traction against the rail.
