Improved Frankenstein
thingiverse
I discovered that using two LM8UU bearings significantly reduced twisting movement. To further enhance stability, I conducted an experiment with four LM8UUs in the bearing carriers, replacing the original two LM8LUUs. This redesign also enabled me to repurpose the other arm for a Tronxy square proximity sensor positioned close to the nozzle (offset 38.5mm). In addition, I modified the heatsink duct to accommodate a 40mm fan instead of the stock 30mm fan and added a ring duct to the target cooler. A few minor improvements were also made: nut traps for easier assembly, a bracket on the front right bearing carrier to manage cable ties, and hollowing out the bearing carriers to reduce weight without compromising strength.
