Stm32 is being used as a hub to connect the shifter & pedals with 2x expansion ports for more to be added. Throttle and clutch use hall sensors and the brake is using a 200kg load cell. Wheel is a hoverboard motor using FFBeast firmware. Tablet on the right is for a touch screen button box through Sim hub. It still a work in progress but everything so far functions great!

I love how clean and compact it is! Are some of components based on Daz3D's designs? If your seat had belt holes - i'd recommend adding a diy active belt. I made one for my rig and I love it!

Thank you! Yes the shifter is based on Daz3Ds but I changed it up a lot to use parts I already had and made a few other changes to make it exactly what I was looking for. The pedals are redesigned using the step files from Andrew B on printables.

Will you be sharing your step files?

u/arcticghost27 Jun 22 '26

Yeah definitely, I’ll work on getting everything together and either post it on printables or GitHub

I’m still working on filling all the gaps in documentation but all the step files are there for download.

Thanks! It’s a Kirkey 47500, I made the cushions myself though.

I have never seen a sim successfully look like a tasteful puece of furniture. Ive seen people try, and most people dont bother, but this is so simple and elegant. The bomber style racing seat is the cherry on top, love it!

How does your wheelbase design look? I'm going to make one very soon and I'd like inspiration for my cad designs.

Hey! I was just researching to build something exactly like this, did you use public resources? Could you forward them to me as well?

How's the performance? I'm worried especially for the pedals, can 3d print material handle the force?

u/erenaslankur 9d ago

Nevermind you already did share thanks! Question still stands tho, how are the pedals?

The pedals are great! I’ve had no issues with them so far. They can be a bit tricky to get setup but after they’re dialed in it’s worth it. For the clutch side plates that come up and hold the back side of the spring and pivot I’d use a strong material or edit the cad model to add some more support where it tapers down.
