This is the loading Hatch to replace the original from issue 1.
This hatch was created by measuring the part from issue 1, and gathering dimensions of the hatches from video's. also images of the hatch were viewed to add the detail.
I have also included the skechip file for others to alter as required.
It is alot of work to design these parts, and I'm happy to share. But remember where you got it from if you use or modify.

This is still in development, and might work better with a resin printer.

Check fitment, & use hole in bottom of part to attach to deck
