This design is a Stick Shift Knob that should fit most sim racing setups. It fits perfectly on my Logitech G920. I also added a whole in the back for a metal screw in case your fit is too loose, and needs some tightening. It feels great in the hand, especially when it's wrapped in sewed fabric (like I did). Check out my website, https://www.mattiatbutera.com for a more in-depth explanation or my Instagram https://www.instagram.com/mtb_3d/ for more projects! If you are going to wrap it in fabric, I recommend you follow these steps and/or watch this video: Video: https://www.youtube.com/watch?v=KamEc8Fi87Y&t=2342s Find 3 pieces of fabric/leather Cut them to the size of each face of the knob, but make sure that all the edges can touch Sew 2mm-3mm all around from the edge of each piece Tape/glue each piece to the corresponding face on the knob Sew the edges together, threading through the previous stitch in a zig zag pattern Cut a whole in the back for the screw if needed Put it on. All done!
