Geeetech mini rostock delta g2s pro linear bearing

thingiverse

Replacement linear bearings for the carriage. 45mm long, so twice the length of the original metal LM10UU or drylin 10mm linear bearings. These have no slop on the rods and are a tight fit. They are less than half the weight of the original holders and metal bearings. Ive included 8mm versions because I could. They have no use on the Geeetech mini delta. I designed these longer bearings as an alternative to adding an additional bearing and increasing the size of the carriage. The longer bearings did not fit the existing plastic bearing holders so I incorporated the holder into the design as one piece ready to bolt in place with the existing m5 nuts and bolts. Ive included simple printing supports in the design. You can add support material with your slicer but I found Nylon didnt need any extra support. I have printed these in Taulman Bridge Nylon and they are a great fit and there is no slop in the bearings. Once reamed they ran freely on the rod. Update: 13 Aug 2017. The 10mm bearings stl is a very tight fit on the 10mm rods on my Geeetech G2S pro. I reamed them with a 10mm straight cut reamer but still too tight and sticking. I either need to ream them a little bigger or print with more clearance on the internal diameter. Awkward and time consuming to test as Im using the machine and have to dismantle it each time to test.
