Kit for the Z axis threaded rod. Smartrap Core

thingiverse

Largest printer demands two carriages. Meanwhile, belts are failing miserably. I created a custom mount for bolts inspired by the Prusa Mendel design. To complete it, I needed an M8 threaded rod, two bolts, and a spring - it actually works perfectly! At the top, there's a bearing labeled 608zz. Not to mention another one, labeled lm8uu. Printable space is set at 500 × 500 mm. Originally, Z-axis had shafts with 60 mm distance in between, but I've upped it to 120 mm for enhanced performance. You can check the other version, where the rod gap remains at 60 mm - it's part of the collection at http://www.thingiverse.com/groups/smartrap
