X Carriage - Sovol SV06 Plus (three parts)

thingiverse

This is a replacement print for the Sovol SV06 Plus x carriage. The model comes in 3 parts and does not need glue to be assembled.Note: this carriage is slightly longer in the z-direction than the stock carriage because it has some added length on the bottom of the carriage. This is to allow room for the M3 nuts to clamp everything together without hitting the extruder pcb. Print instructions:Material: PETGLayer height: 0.2mm for the middle part, 0.3mm for the front and backPerimeters: 4 (this is really important for strength and threaded inserts!)Infill: 40% (not critical)Orientation: flat side on the build plateSupports: no support or brim required. Support could be used for the screw holes if your print sags too much thereExtra materials needed:M3x20 bolts (6x)M3 nuts (6x)M3x4 threaded inserts (3x). I bought these: https://www.tinytronics.nl/shop/en/tools-and-mounting/installation-and-mounting-material/threaded-inserts/threaded-insert-m3-4.0mm-20-piecesI used an old soldering tip at 300 degrees Celsius to insert the threaded inserts into the 3 holes in the front part of the carriage (see photo). See this manual for detailed instructions: https://hackaday.com/2019/02/28/threading-3d-printed-parts-how-to-use-heat-set-inserts/Assembly:Insert all 6 bolts into back carriagePlace back carriage onto bearings and insert timing beltsPlace middle carriage onto back carriage and screw in all bolts. Add the two nuts for the centre holes and tighten centre bolts until nuts are securely receded into recesses (see picture)In front carriage, insert nut into top right slot until holes are alignedPlace front carriage over middle carriage and tighten top right bolt. Then screw nuts over remaining bolts and tighten
