Hello again! If you update the 757/767 TQ designs at all, I highly recommend adding some material and enlarging the 3mm screw holes to allow for threaded brass inserts. I tried using one on the current design and upon insert it sank way too deep given the lack of appropriate material underneath and to the sides of the holes. The reason to use the inserts IMHO is for a much tighter clamping force on the cover plates on the handle to get rid of any unsightly gaps.

Karl,
Was thinking the front and back covers on the throttle handles (12 and 13), and the 3mm holes for securing the outer cover sides on parts 39 and 40. Mostly I'm just worried about having a perfect print and then stripping one of the bore holes out. A TBI should alleviate that.
I ordered the below when I was working a different project. The guy who made the Mk4 X-Carriage for the Anycubic Mega S had a separate version of the STLs for those wanting to use these and it was highly recommended.

Looking at the Mk4 differences, I believe the main difference is the holes were enlarged slightly to allow for a tight fit of the insert, and extra material was added to the walls to give the insert plenty of plastic to grip once it melts and cools.
Hi Tom, What parts are you thinking about? I can certainly modify the parts and any chance you can send a pic of the inserts so i can try to get hold of them for protyping? Kind Regards Karl
