FLSun SR Super Racer - HGX lite & CPAP cooling (Sherpa mini added!)

Here's a mod for the FLSUN super racer end effector. (I have now uploaded a main body which accommodates sherpa mini.)

Using a HGX Lite extruder and 3x 5015 fans you can convert the bowden setup to direct drive with improved cooling.

There are only 3 bespoke parts to print - the extruder mount (x1), nozzle ducts (x2) and 5015 fan mounts (x3). all of the complexity is in the main body. The hot end heatsink will need modification - the bowden tube mount needs to be trimmed off leaving only the basic heatsink behind - this should be 25mm high.

The hot end cooling fan also bypasses air towards the extruder stepper motor to control temps

4x m3 heat set inserts required for the extruder mount & zipties for wire management and fan mounts.
