Use these parts to build LED gates for tiny whoop track. You will need to buy 16mm oval conduit which costs 75p for 2m from screw fix or Wickes

For the mirror tunnel buy A3 acrylic mirror from eBay. its 5 sheets for about £10. 1mm thick may sound thin but some hot glue and conduit and it works a treat

LED's you can use anything banggood have some for about 2.50 for 5m. Addressable works nice on the warp tunnel and mirror tunnel

These are designed to be a tight fit on the conduit but the conduit tolerance is pretty poor, I found about 10% of my joins needed glue or a hot air gun to make it fit.

These parts are inspired by the ones from Cerberus, if you want end pieces, square or square gate feet see his V2 designs.
