as my aim was not to use hot glue (not a drop use)
i needed the componants to fit in perfectly, so some case mods in the form of 3d printed parts were in order
i used wermy standard set... button wells, switch ledge, cart reader holder and screen bracket (which i never used)
all of these were ok apart from the screen bracket, as this really needed to be hot glued onto the screen (not an option, something else needed)
i found this on thingverse, i could epoxy it into the case making it rock solid and slide the screen into place (it holds it perfectly without glue or tape)
next was the tactile switches at the back, most builds i saw had them encased in hot glue (didnt like the look of that)
so with my basic (i mean basic) 3d design skills,
i came up with these, they do need some modification to fit either with a knife or dremel to set the hight depending on the switch used
these are epoxy to the case, but the tactile button are just pushed in
next was the power boost, while looking on thingverse i also found that someone had already made a housing for the power boost (thanks to them) so no worrys about shorting and more importantly it could be taped (VHB tape) to the gameboy and the power boost fits snugly inside
finally i knocked something up for the pi zero (held in place by vhb tape, botton side to screen & top side to sd card holder on the pi)
i did also pinch from thingverse a design for a usb socket holder and modified it to fit into the gameboy
and made a couple of L shaped parts to be printed which i used for the volume wheel and power socket (these can be seen in the first post)
i dont have a 3d printer and used mainly 3dhubs
NB: i had everything printed in abs... this would hopefully eliminate parts getting soft (especially the power boost holder and pi stand)
