Customizable 5V relay case (updated version)

thingiverse

I created this case to use with an extension power cord: I wanted to safeguard the 5V relay board and allow some room for wire connectors. I updated my initial version of the 5V relay case to add more features: - If you want to make the case wider, you can decide whether the relay will be centered or aligned to the left or right. - I designed four support types and you can choose one for each support: - 0: the simple support like my first version - 1: the same as 0 but with a column in the lid to prevent the relay from moving up - 2: to use a bolt (M3 x 6mm) and a nut to secure the relay board on the bottom of the case - 3: to use an M3 bolt to screw together the bottom and the lid (screwing directly into a column in the lid) To customize, measure the distance between the holes on the board (check the sketch for the most important parameters). I have various clones of this board and the hole spacing is not exactly the same (20 or 21 mm).
