We are always trying to update our products and keep making them better, stronger, easier to install and last longer. I have recently been testing out heat inserts. These are brass inserts that are pressed into the 3D printed part while being heated with a soldering iron using custom tips. Since they are heated and pressed in they have great adhesion to the plastic and have less issues than the previously used screws or bolts with nuts. I'll be updating each of the product pages as they get upgraded and tested. Some products, like the auto to manual covers, will not get these though as I feel the current configuration is better. The picture above is for the 90-91 S2K cluster mounts.
