Voyage Megan Ball Mount Plate

Update (2024-09-24) [V2]: 

Revised the model to allow for an M5 bolt to pass through the body/ball to prevent neck snapping. Secures to the ball with an m5 locknut. (Bike was knocked over and it broke exactly where you'd expect it to.) 

Additionally, the pass-through hole was enlarged to 10mm and a “snap in” ring for 5mm was devised. This way you can add/remove the soldered JST wire without having to solder with it in place or tear the back piece apart to get it off.

This is a ball mount backplate for the Voyage Megan VESC display.

Lots of cellphone mounts come with this ball mount clamping system, so I made one to fit the Voyage Megan. There are a few other quirks to the design as well:

1. The M3 bolt holes are “blind” holes – they don't go all the way through; use M3x6mm bolts
2. The M3 bolt holes have chamfers to make it easier to get them threaded
3. There is only a single round, 5mm hole in the backplate – it is expected that you convert from the JST connector to a 4pin Julet connector – the stock JST connector isn't long enough and it's a good idea to have a short, disconnectable, waterproof connection coming from the box

Otherwise, print in a sturdy material with lots of infill and many walls. (I did petg, 25% gyroid, 4 walls.)

I've included high resolution STEP file for direct printing and the Fusion file if you'd like to tweak things (mostly, there is no standard for the ball dimensions; so you might need to tweak that).
