Laser show for poor man

Step 7 Let's build tiny house

It's a good habit to keep dust away from optical staff, so our device needs hermetic enclosure.

I had Hammond 7x4x2 box lying around, so I put it in business.

Since we determined optic configuration and beam path we can mark and cut out window.
Then get square piece of transparent acrylic and glue it to its place.
Next drill one more hole for power jack, glue it, connect to board and we are done.

How easy are these enclosures to drill?

Hammond box is made from PVC plastic. It's a soft material and it's very easy to work with.
