Z Threaded rods ball bearing guide
thingiverse
I recently changed the 30mm standard (and bent) threaded rods with better quality (and straight), but 40cm instead. So, i designed this add-on for my z axis top bracket (http://www.thingiverse.com/thing:1637438) to guide the rods, and with the added ball bearing to minimizing friction. If you are using 30cm rods, i also made an adapter, just attach it firmly with a cable ties on your rods. The ADAPTOR need RAFT due to really small base, print it with the open end up. The GUIDE need SUPPORT, print it like in the photo. Print Settings Printer Brand: RepRap Printer: Prusa i3 Rafts: Yes Supports: Yes Resolution: 0,2 layer, 0,3 nozzle Infill: 20
