Flipsky motor mount for Axis alloy mast - internal cable

A motor mount to allow a Flipsky 6374 or 6384 waterproof motor to be mounted to an Axis alloy mast. 

Cables are able to pass into a hole cut into the side of the alloy mast. The print is secured to the mast with two M4 socket head screws. When mounting I suggest that the pod is held against the mast and the holes on both sides of the mast are scribed through with a sharp pointer. Remove the pod, then centre punch drill points a mm or two further in. Drill through using the centre punch marks as a guide - then carefully file with a 4mm chainsaw file to extend the holes back until the bolts 'just' pass through the pod and the mast. Its super easy to drill the holes in such a position that the clamp is loose, this technique helps minimise that possibility.

The other detail worth noting is to very thoroughly de-burr the cable hole into the mast and through the mast base both inside and out. The Flipsky cable silicone sheath is extremely soft and prone to damage. If it is damaged salt water will enter through the cut and work its way up inside the sheath, corrode the cable and lead to motor failure. Use heat shrink or other protection around the cable where possible. 

I print the pod with 6 outer layers and 15% gyroid pattern infill. After printing I drill two 5mm holes through the base, just into the print. I then use a syringe (no needle) and inject regular slow cure epoxy into the print, allowing time for the epoxy to completely fill the print, you need to be patient and slowly keep topping up the pod supported in something like an egg cup. This results in a super strong finished part. My preference is PCTG but PETG also works fine in my experience. 

The small caps can be glued in place with a dob of regular silicone or hot melt glue - something that allows easy removal to access the motor bolts. A 4mm allen key will pass through the cap mounting holes to tighten the motor bolts
