Shorter Plastic Hypercube Z Bearing Carriage LM12UU

thingiverse

I modified this for my 400x400 Hypercube Evolution build using the dual z stepper motor setup. I bought the plastic LM12UU polymer bearings instead of metal ones because they are shorter than other models. To hold the bearings in place without nuts and screws, I added inner rings; however, you can use them if you prefer. Since everything is a tight fit, I used a rubber mallet to tap the bearing into place after installing the part onto the metal rails. You'll need to install the part and tighten the t-nut screws first or it gets in the way. Bushing Dimensions: 21.8mm x 21.8mm x 31.8mm Optional Hardware: M3x25mm screws M3 standard nuts
