A simple adapter for the SOVOL SV03 X carriage so you can enjoy a proper MN12H linear rail! No more binding V-Slot Wheels!
1. Get an MN12 linear rail about 40-43cm (I used 40cm it's a standard size) 2. Get a bunch of M3 sliding nuts (16 for the 40cm rail, add 2 extras for the ends) 3. Equal amount of M3x6mm screws and 2 somewhat longer ones (10mm) 4. Take your X carriage off, get rid of the wheels and their standoffs 5. Loosen the X belt tensioner just enough so you can slide in the nuts to the top of the bar 6. Attach the Linear rail to the nuts with the short M3 screws, make sure you leave one nut extra on both sides 7. Put the longer screws to these extra nuts to make sure your slider does not go off the rail 8. Print the adapter piece it mounts to the top of the slider. You will need 2 short M5 screws as the originals on the X axis are way too long 9. Mount your X carriage back as it was, don't forget to re-level your bed and update your mesh
+1 if the rail is not long enough you might need the little end-stop widget (included) so the carriage hits the X end-stop properly
