CTC DIY Upgrade to new threaded rods

thingiverse

These two parts allow you to upgrade your CTC or any other Prusa-Clone to utilize new threaded rods. I have replaced the rods with more accurate ones. The anti-wobble units are designed for easy swapping and can be omitted, but it's recommended that they're used. The adapter is printed from flexible filament and replaces the rubber tube in my setup; others might have a metal component connecting the stepper motor to the rod. A flexible connection has several benefits - it automatically aligns itself to the correct midpoint, resulting in exceptional print quality. The new spindles I'm using feature an 8mm ascending slope, and they can be purchased for just 12 Euros from China. They include the spindles along with a brass nut. Assembling these parts only takes minutes; perhaps half an hour at most. To utilize other values on your z-axis, you'll need to upgrade your firmware. I now use 800 steps per mm (utilizing 32 microsteps), whereas if you're using the original pololu-parts, you'll require 400 steps.
