Printrbot PLUS V2 Top Stiffener Bracket for M8 hardware

thingiverse

The straightforward and efficient bracket easily attaches (requiring potential adjustments) to the top of 2 x 12mm smooth rods on the Printrbot PLUS V2. It is designed for holding M8 threaded rod and M8 nylock nuts within recesses. To regulate the pressure exerted by the brackets on the rods, use a plain or nylock nut on the opposite end. The top hole may be expanded to serve as a filament guide or for mounting other items. I discovered that the Printrbot PLUS stock had a 5mm difference in distance between the smooth rods' bottom and top, causing X rod shifting along the axis. This bracket enables adjustment to achieve perfectly straight smooth rods. Enhancing print quality by adding a stiffener at the top of this machine is beneficial.
