Canon EOS 400d connection cover replacement

The model needs to be printed with supports, I got best results using snug support style and limiting support to do not touch the main body.

In the 3mf project included you can see my settings for the print.

I lost the original rubber cover so the design has been a try-to-guess process,  you can see all the failed prints in the attached photo.

I finally printed with PETG, with PLA the latch breaks apart after the first attempt to open the cover.

Ideally it will work fine with TPU, For the time being I have no TPU spool, nor printer to try the print. 

I would have adjusted the height to make it fit better in the socket but sadly my printer has failed and I am waiting for replacement parts.
