42mm cnc spindle cover and switch top.

A press-fit cover for the standard 42mm spindles that come with cheap CNC's like 1610's etc. Protects the terminals and provides a outlet (either side) with slots so a cabletie can be used for strain relief.

Needs support to print due to the internal terminal channels. For me the press fit worked perfectly, your mileage may vary.. I am using a very rigid 'flexible' PLA for the toolhead bits of my CNC so I had a bit of flex to play with. I'm basically assuming any CNC owner worth their salt will be able to get this fitted snugly.

• take care about clearance to the Z lift motor! I kept the design as flat as possible at the back but still only have 2mm or so clearance.
• dont block the airholes, they are important.

Top cap is separate; a blank one is provided you can drill/customise yourself, plus versions with a standard 12mm rocker switch and LED hole (I used a big 8mm led I had lying around unused and unloved..)

Scad file included; feel free to customise/comment etc.
