Sturmtiger Loading Hatch Assembly

This assembly is to replace the moulded parts on a 1/16th Torro sturmtiger RC tank.
The frame part is placed in from the inside after the original moulded pars are removed and glued into position.
The 2 hatches are made in 2 parts an upper and lower section these are to be glued together with some 1.75 filament used as locating pins the hole in the small hatch is for the Nahverteidigungswaffe that is here https://www.thingiverse.com/thing:4061733.
The small holes are for the handles that I made from copper wire and the 3mm hole is for the jib mount that i made from some 3mm brass rod.
When fitting the large hatch has a small tab made from thin brass sheet to hold the front edge down and the small hatch when closed holds it in place.
The small hatch is held by small pieces of copper wire at the hinge the bracket on the underside is for fitting a stop mechanism or attaching to a servo.
