Smartcore Z axis Threaded Rod Assembly

thingiverse

I'm designing a smartcore with a threaded rod and linear rails. It features two threaded rods and four rails, with one rod and two rails on each side, powered by two motors that work in tandem. To ensure the two sides align perfectly, I built a frame that fits snugly over the rails, threading them together securely. While the design is sound, there may be some slight flexibility or "wriggle room" in certain areas. Here's what I need to bring this project to life: * 4 x SC8UU bearings (available on Thingverse or by purchasing aluminum parts) * 2 x TR8 Lead Screw Nut Housing units * 2 x flexible couplings * 4 x KP08 components
