Canon EF Body Cap (Openscad)

Dimensions from Canon EF 55-200 zoom measurements.
Tested with 350d and 450d bodies.
Could be used as a base for others developpments (Parametrical format = openscad)

History:
I met some problem with a design on this site (https://www.thingiverse.com/thing:198816) because I needed to use Dremel with it :/
So I decide to take the measurements by myself.
I use a zoom as reference hoping to be compatible with most of camera bodies ...
