These aluminum uppers well help strengthen your frame like the TAZ Workhorse and the TAZ PRO
Instead of the 3d printed only piece, this is an aluminum upper that attaches to a 3d printed lower assembly that will hold your bearing and your smooth rod.
If you move your printer around at all this will help keep things more rigid then with only 3d printed z-uppers.
Pair this with our frame reinforcement kit, and get your frame as rigid as the Workhorse and PRO printers.
