thingiverse

Hello everyone! It's been a while since I last posted something. Let's get back on track! This is my brand-new Y-axis carriage. Now, I'm utilizing MGN12 rails and MGN12H carriages instead of wheels. Also, I've placed them at the bottom of the profile - this setup looks much better to me. #### Where I purchased the rails: - 2 x [MGN12 Rails](http://ali.pub/2ddiy5) (390mm length, holes spaced 7.5mm apart on both sides) - 2 x [MGN12H Carriages](http://ali.pub/2ddjpy) (With an "H" at the end; I highly recommend getting one extra for emergencies) Before assembly, I applied [Castrol LMX grease](https://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/B215DF5968A78AE680257796002FEFA4/$File/LMX%20GREASE.pdf) to the carriages. #### To assemble one carriage, you will need: 4 pcs - M3x35 screws (or M3x40), for main part assembly 2 pcs - M3x25 screws, for bearings 4 pcs - M3x10 screws, for mounting MGN12H carriage 2 pcs - M3 self-locking nuts for bearings (if you don't have them, regular nuts will do) 4 pcs - M3 regular nuts 10 pcs - M3 washers 4 pcs - M5x10 screws, for aluminum profile 4 pcs - M5 square nuts 4 pcs - M5 washers To mount each rail, I used 4pcs of M3x10 screws with [T-nuts](http://ali.pub/2ddld2).
