Aliexpress 2750KV Motor Mount

This part mounts the no-name 2750KV multirotor motor linked below to a 6mm OD carbon fiber tube. The wires pass through the tube for a clean setup.

The part also has a cavity which fits a 5630/5730 LED pointing down through the print (if you use a translucent material.) It's a tight fit so make sure your wires don't contact the motor's shaft or E-clip. Mag wire is recommended. 

Each pod weighs about 1g. The part is best printed with the motor side up. I recommend a brim to prevent the arm tube hole from warping upwards throughout the print, as there isn't much material there to support it. I printed the pictured mount with Inland PETG using the following settings in Cura: 

• Layer Height: 0.2mm
• Wall Line Count: 3 
• Top/Bottom Thickness: 0.8mm 
• Infill Density: 30%
• Cooling fan: off
• Adhesion: Brim, 3mm 

The part can probably be printed a little lighter but I haven't tried reducing wall thickness or infill density. With the above settings it is very robust. 

This print requires some manual processing. I remove the brim from the part and use a half round file to clean up the arm tube hole, removing any blisters of material and smoothing out the steps between layers just enough to get a tight fit over the tube. I also drill out the motor screw holes with a 2mm bit for a better fit, though it may not be necessary.

I use 3mm long M2 screws to secure the motor to the pod. Their heads are about 3mm in diameter.
