Ender3 V2 Spider DirectDrive Carriage

You'll need 9x M3 plastic inserts and M3 screws &cable ties. One more insert is for future upgrades (close to motor). Cable ties should be placed before mounting motor.

Mounting radial fan with screws is optional (not necessary when cover plate is placed).

Two long pipes on fan blower part is just for easier printing (anchors), cut-off them after print.

Cabling should be extended and directed at front of frame, otherwise you'll be not able to print high objects or cables will block path of carriage at X min/max. 

Length of PTFE tube between extruder and radiator is 40.5mm

Probe offset is x=-25mm, y=-5mm 

Unused hole on fan is for long Allen key = mounting carriage bottom wheel.

Don't forget to change retraction settings at slicer to lower values ( ~0.8mm instead of 5,5 ) after upgrade. It's recommended to check metallic carriage plate dimensions before printing project.
