My attempt at modernizing the Malyan M180.

Goals:
Reduce weight on gantry.
Modernize electronics
print flexible filaments
General usability, easy to load extruders, usb port up front, wifi probably
rework spool holders for new extruder location

What's Included:
New carriage assembly with cooling shroud and cable retainer
E3D Cyclops hot end mount
Creality Mk10 style hot end mount
part cooling duct and mount for a 4010 blower fan (24v blowers are what ender 3 uses so its easy to find)
stepper mounts for for bowden style extruders
bowden extruders based around the gears from the stock extrudes, there is a mirrored set but its not required you can just flip it upside down and it still fits ( i just liked the look of them mirrored :) make sure to reverse extruder stepper if using the mirrored setup
limit switch mount for Z axis to use regular limit switches (the optical one incuded with mine seemed to be non functional so this is very much an optional part)
MKS GenL Mounting plate
Reprap discount full graphics display mount with USB Port (fits startech USBPNLBFBM3 )
I didnt bother with spool holder redesign i just use this https://www.thingiverse.com/thing:3020026 which is better than anything i would have designed anyway =D

I found that the steppers this printer includes like to run hot no matter what i do with the VREF they're either hot or have no torque so i created a stepper cooler to keep it under control they use 30mm DC fans you can find them here https://www.thingiverse.com/thing:3525307

keep in mind this is a 24V system not a 12V system so 30mm fans can be harder to find, i got some on banggood for $2 each

Adding CAD files as i find them
