Introducing the Spool Heads Racing SR1 3D printable 1:64 scale diecast racing track (Hot Wheels compatible).

Here are the instructions on how to make your own compatible SR1 track pieces:

Here is the launch video which shows off the track pieces: https://youtu.be/swgDecW7Sdo

Spool Heads Racing SR1 track series is inspired by the mallemattias 45 degree curve. I needed to modify it to fit with Adventure Force Nascar Crash Racers track so I started from scratch in Fusion 360.

This is a relatively low speed track and doesn't do well with high profile diecast cars. I have plans to also add larger radius turn and banked versions in the future, as well as single lane versions.

The turn radius is 210mm. Multiple turns can be connected to create a 90 or 180 degree turn or chicane or serpentine curve.

The 190mm dual lane straight track is designed to be printed on smaller build build plates like the Ender 3. The 254mm dual lane straight track is designed to be printed on larger build plates like the CR-10.

These are all compatible with the SR1 track spacers, Adventure Force Nascar Crash Racers, and Hot Wheels Track. You can even use the Hot Wheels blue connectors if you'd like.

If you print this track, please let me know what you think of it and if you have any suggestions or questions. Thanks!

2022-01-13 UPDATE: Modified the inside wall on the dual lane tracks to fit better with future single lane track. Also included a Fusion 360 files with the sketches of the single and dual lane track so you can make your own designs. Or in Fusion 360 go to "Insert" and then selected the DXF files that are also included in the downloads. Thanks!

2022-01-18 UPDATE: Added the SR1 22.5 degree turn.

2022-01-28 UPDATE: Added SR1 140mm dual lane track and SR1 45° turn with 300mm radius.
