Racing Shifter Knob for Logitech G25/G27/G29/G920

I printed Danid87's shifter (2549977) but the screw collar broke really quickly and the shifter kept spinning around. I wanted it to be screwed directly into the shaft. There is a 2 layer bridge inside so will need to use a 4mm drill bit to open it up (i did this by hand). You will need a 40mm M4 bolt to secure it down to the shifter. v2: Removed bevel from shifter and moved to cap H Shifter: https://www.thingiverse.com/thing:4302821
