Canon EOS-m Battery switch defeat

This device slides in next to the SD-Card to fool the battery cover switch when using an external power supply with the Canon EOS-m (original) camera.

The external supply was an ebay purchase and can be found here

Once this little part is added it all works perfectly.

I printed this in PLA at 0.05 layer heights,
