SV04 Upgrade - Micro Swiss NG Direct Drive Extruder - Mount and Fan Shroud

Description

I've found a few mounting brackets and shrouds for the MicroSwiss Left hand configurations, but none were a complete fit or offered L & R hand compatibility. Check out the MicroSwiss NG Direct Drive Extruder for details: [MicroSwiss Store](https://store.micro-swiss.com/collections/extruders/products/micro-swiss-ng-direct-drive-extruder-1). This package includes both left and right brackets, as well as the fan shrouds. When printing on a dual extruder, avoid mirror printing since all parts have slight differences. I recommend printing the brackets at 100% for maximum solidity and the shroud at 25%, both with supports. Although I've redesigned the models from scratch, the original bracket design that inspired me can be found here (with better installation photos): [Sovol SV04 Micro Swiss NG Mounting Bracket](https://www.printables.com/model/519124-sovol-sv04-micro-swiss-ng-mounting-bracket). Both shrouds are compatible with a 4020 box fan and a 5015 blower fan. **Left Mounting Hardware:** - 5 x M3 heat inserts - 3 x original M4 screws - 2 x M3 25mm screws - Make sure to route the bed leveling probe through the trench on the back. **Right Mounting Hardware:** - 5 x M3 heat inserts - 4 x original M4 screws Additional screws from the extruder package, along with some M3 nuts and screws for the fan shroud, are needed. The exact lengths escape me, but the setup is straightforward. Below, I've included my adjusted Marlin values as a starting point, though you should recalibrate as necessary. "#define NOZZLE_TO_PROBE_OFFSET { -6.3, 21.8, -3.45 }" "#define X_MIN_POS -55" "#define Y_MIN_POS 0" "#define Z_MIN_POS 0" "#define X_MAX_POS 288" "#define Y_MAX_POS 310" "#define Z_MAX_POS 360" "#define DUAL_X_CARRIAGE" "#if ENABLED(DUAL_X_CARRIAGE)" "#define X1_MIN_POS X_MIN_POS" "#define X1_MAX_POS X_MAX_POS" "#define X2_MIN_POS 25" "#define X2_MAX_POS 365" "#define X2_HOME_POS X2_MAX_POS" "#define DEFAULT_DUPLICATION_X_OFFSET 144"
