E90 Pull Strap Conversion

YOU HAVE TO CUT OUT A HOLE IN YOUR STOCK HANDLE CUPS FOR THIS TO WORK PROPERLY. There simply is not enough room in the cup for a strap to comfortably sit. Stock pin works, same with the cable and attachment. You need to keep the creamy-white piece and it still needs to be able to click in and stay there. I have attached how I cut mine out using a Dremel and it works just fine. Has a cutout for an M4 hex nut and angles to make sure it doesn't contact the cup, but I attached an editable fusion 360 document if you want to change it at all, though I should mention the component named "outside" does not fit the stock handle cup.

I paired with these:
Nylon webbing of some kind OR whatever strap of choice
"Grommet eyelet kit" - makes a clean hole for bolt to go through
Assorted low range M bolt and nut kit - got mine from microcenter and that's what I designed this for (Inland Bolt Set 330pc - $4)
