Working N Scale Bogies and Wheels for FDM or SLA printing

thingiverse

These work and roll, ready for attachment to your 3d printed wagon of choice. In the future I hope to make detail parts (roller bearing side detail) which can be printed horizontally and glued on. These are intended as a base for scratch building, the wheels are designed to n-scale spec, except the flanges are double width, and the tread is +02mm wider. I have not exhaustively tested these, I currently don't have an N scale layout, but here is a quick demonstration of rolling on printed track. https://www.youtube.com/watch?v=f7oO8SHex5A These were designed with SLA printing in mind. There are two versions of the bogie: (1) a safe version, which should give you no grief on any FDM printer, if printed slowly and carefully; and (2) a minimal version, which is a challenging print for an FDM printer, particularly if your retraction settings are not dialled, but should be ok for SLA (I have not tested this as I only run FDM) The wheels work with either version. A normal staple (as found in your household stapler) is the axle. On FDM they are best printed at a resolution of 0.12 or below, and very slowly (<10mm/s)
