Designed to be used with 3/4" PVC piping of any size. These are meant to be modular so that you can make various different combinations to build any basic track you want using the pieces. Optionally covered with jumbo pool noodles for impact mitigation. Perfect for sub-250 races since the foam will survive quite a beating from that weight class.

First track test using only angled and t-connector:

This is a work in progress. I plan to add more connectors to this as I make/test them.

Print in TPU. Ideally with a lot of walls top/bottom and infil to make them extremely strong and resist flex. I've printed mine with 16 walls and 25% honeycomb infil, which seems to be great. Print on the flat end, 0.2mm layer heights. No support should be required. You may want to print with a wide brim as warping will cause problems getting PVC pipe inserted and you may have to painfully remove material to make it fit otherwise.
