Vỏ Subcompact OWL (Subcompact OWL enclosure)

This holds the compact owl, just like the pre-existing enclosure - Download and use Tray.stl from it.

I've called this the Subcompcat OWL enclosure since its submarine like - makes a good bath toy.

I wanted to reduce part count (while i was waiting for parts), and make assembly faster. I haven't installed this myself (yet) so i may change the way it mounts in the future.

Print the blank back plate and test for water tightness in a bucket of water before putting any electronics inside.

Choose a main body and backplate to suit.

Required

• Metric o-ring R-25 34.5x3.55

• plumbers tape - wrap each thread (and the backplate) about 5 times

• 37mm K&F uv filter (same as other enclosure)

print settings:

• Modern 3D printer with high accuracy

• Arachne wall generator

• 0.3mm layer height (works better for the threads)

• Make sure seam position is nearest - aligned isn't good for the threads
