Hi. I've made this model to help you with replacing your broken hinges in simoverts ;)
Printing orientation is quite tricky. It's personal and depends on a printer you use, but I belive you can figure it out. For me crosswise worked best.
PA12 or similar is strong enough.
You will have to use a small flat-headed screwdriver to fit the small pins in place nicely to the front cover's mounting. Then just push the bigger pins into the holes and it's done.
