Sim racing parts for aluminum profile rigs

Made for 4040 aluminum profile sim rigs

Most aluminum profile rigs use 40-series extrusion with an 8 mm slot, and that's what these parts are made for. Each one mounts with a roll-in spring T-nut and a bolt, so you can add it without taking the rig apart and move it later. On a 10 mm slot the bolts still fit, you'd just use your own T-nut.

The mounts are free to download if you'd rather print a different height or angle: Downloads.

Made in BC, shipped from Canada

Everything is designed, printed, built and tested in British Columbia. Prices are in Canadian dollars. Orders ship within Canada, and shipping is added at checkout. For the US, email me first: tariffs keep changing and I'd rather you know the full cost before you order.

The Matrix Effect Builder draws LED matrix effects for SimHub and gives you the code to paste in. It's free, runs in your browser and has no sign-up.

There are also guides on mounting parts to 4040 extrusion, setting up flag LEDs in SimHub, and choosing button box switches.
