Anet A8 Orballo steel - Z-axis smooth rod & leadscrew holder

thingiverse

Orballo Anet A8 steel frame version of Tatara is not held to Tatara standards for smooth rods holes, resulting in some play. The rod can be secured (up) using a screw and a nut, but I wanted to incorporate a lead-screw holder into the solution. Having 608ZZ bearings on hand led me to use them. Please note! I'm uncertain if fixing the lead-screw is a good idea for this printer! In fact, I'm pretty sure it can make things worse (quality of prints, durability of leads-screw, etc) if the lead-screw is not perfectly straight and properly aligned (which is very hard to do). But since this steel frame is very sturdy, my lead-screws are very straight and I spent a lot of time aligning them perfectly... I decided to test it. #TODO: Smooth rods wobble at the bottom too. I'm currently designing those as well. Since screws from Orballo i3 Prusa package are also too long for my steppers, I'll try to resolve that issue together and implement a stepper screws raiser plate too. #TESTING: I'll be testing and reporting effects of each upgrade in my review of this frame at http://mirko.vukusic.net/3d%20printing/anet-a8-tatara-steel-frame-by-orballo-printing-review/.
