Turnigy Bonsai Battery Strap Holder

This is a battery strap holder for the Turnigy Bonsai flying wing.
The original holder is made from 2-3mm ply and I managed to break it.

This design is the right size for the battery recess in my Bonsai, the dimensions are roughly 55x30mm. Thickness is 3mm at the edges with 2mm in the center, where the 1mm recess provides a gap for the battery strap to run.

I made it slightly more solid that is probably necessary as it is also helping hold the wings on my bonsai together. Damn these thing
