The Grip Spec II is built to be easy to assemble, giving you the good stuff you want without the price tag that usually comes with it. It features over 35 inputs, LED backlit buttons, a custom PCB, five rotary encoders, five-way hat switches… the lot. Sleek, capable, and genuinely affordable at just over £90 fully built. It’s USB powered, and you’ll just need a universal wheel hub adapter to get it mounted to your wheel base.

Quality Disclaimer
This wheel has been tested with up to 12 Nm of torque. It should handle higher forces without issue, but this hasn’t been tested, so proceed at your own risk. Its strength depends heavily on following the recommended infill for each part (found in the instructions), your printer’s output quality, and the quality of the filament used. If it fails prematurely due to excessive torque, poor print quality, or incorrect infill settings, I can’t be held responsible for the outcome.
By purchasing this product, you agree to the above.
Design Notes
"The first actual product I've designed for this venture. I'm quite proud of this one for several reasons. The first is the design of the buttons for the LED variant; printing the unique caps out of PETG allowed me to use more accessible LED momentary, as opposed to soldering individual LED's onto a PCB and rising the costs and complications, allowing customers to solder these at home. The clutch paddles were also another proud moment, utilising the magnets to not only give the force, but also send positional data through the hall sensor; a two-in-one feature of them. The fact that this wheel costs under £100 and has features such as LED buttons and hat switches and is something I'm extremely happy about."
