Hi everyone, I need some help please. I’ve a small hedgehog rescue and found some euro storage boxes the right size to use as stacking cages. They came open sided, unfortunatly without door. I’ve received my 3mm Perspex cut to size this morning, I’d hoped to super glue Perspex hinges but that’s an epic fail! How would you hinge the Perspex door to the box so it’s a flush close (needs to be flush on inside so hedgehog claws don’t get stuck), and no sharp edges in box?
