Working N Scale Bogies and Wheels for SLA printing

Last crawled date: 4 years, 2 months ago

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.

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 SLA printer, if printed slowly and carefully; and
(2) a minimal version, which is a challenging print, particularly if your retraction settings are not dialled.
The wheels work with either version. A normal staple (as found in your household stapler) is the axle.
They are best printed at a resolution of 0.12 or below, and very slowly (<10mm/s)
