Build a Better Speedtrap
thingiverse
Instead of using a box for your Hot Wheels Sparkfun Speedtrap, here is an update 'box' which holds the track and the LEDs/photocells in place better. You will need to change the distance between the sensors to 70mm. Also includes a channel to route the wires to the LEDs under the track. Print it vertically with supports (for the sensor holes). Full instructions on the Sparkfun Speedtrap can be found here: https://www.sparkfun.com/news/2179 Print Settings Printer: Raise3D N2 Rafts: No Supports: Yes Resolution: 0.25mm Infill: 10% Notes: Print standing up vertically How I Designed This Designed using Fusion 360
