Taylormade Flextech 2019 crossover has a strap clip that allows the shoulder straps to slide in relation to each other. I hated it, as the bag tips one way or the other depending on weight distribution (read: beer). This is just a replacement that holds the straps in place. Figured I'd make it look nice and add the T logo at least. Added a clip to attach a towel or whatever as well. It looks like it should fit with the 'lite' version, but I can't confirm. You might need to cut the foldback off the end of the webbing, just use a good pair of scissors and melt it to stop fraying.

I've printed at 0.2 with 3 walls for a bit sturdier piece, definitely strong enough.
