MK180 Strobe kit project box

This kit is perfect for my project but I’m having trouble finding a small project box to fit the board in, I notice the main board has pre drilled holes in it allready for fixing are these just a random spacing or are they set at a standard layout.

I only need to mount the main board in a box not the led snap off bits and a small dpdt rocker switch to turn it on and off.

Do velman make boxes to go with there kits or is just find something big enough and glue it in with mastic

Thanks
