Breakaway Mount for Decorating a Mammotion Luba 2 Mower

I made this to attach a ghost to the top of my Mammotion Luba 2 mower for Halloween.

It attaches via the two rear holes used to secure the camera.  It uses a separate breakaway piece that latches to the bottom so that if the decoration get's ripped off (e.g. driving under a bush or high winds), it won't risk damaging the mower or adapter. You can tailor the strength of joint using rubber bands.

Attaching to Mower

To attach to the mower, remove rear two stock bolts and replace with slightly longer ones (I believe they were (M4 0.7). 

Notes

It's pretty finnicky getting the two parts latched with the rubber bands on.  Align the hooks to the holes and push straight in, pulling each lever out until it slips in the hole and latches.

Then test that whatever you mount to it breaks away easily enough.  Add more rubber bands if needed.  I tested by driving beneath a bush and it came off as designed.

Material

I printed in ASA with solid fill at the bolt points 3 layer perimeters and 25% gyroid infill.  The hooks are printed with 100% infill.  While the retaining hooks bend a tiny bit they don't seem likely to break.  it's holding up. The point on them has worn a little with testing but they are doing their job.

I'm suspicious PLA won't work and PETG might be acceptable.

Here's a video of it in use.
