Rails for lego particle accelerator

thingiverse

I got the parts fora delightful particle accelerator for Christmas (http://jkbrickworks.com, ). However, I did not get the curved track pieces. Since I have a 3D printer, I have designed replacement segments for the ring. I have printed out a set and they work well. The segments are not direct replacements for the track pieces, but are meant to substitute for two curved tracks and associated parts. Since my printer is only barely good enough to make holes for technic pins, and not good enough to make studs, I changed the interfaces a bit. The stl files have slightly widened holes for my printer, but the openscad file can be used to make new stl files if your printer is better at holes than mine.
