Raspberry Pi Pico Mounting Bracket for 4-Channel Relay

I designed a mounting bracket for the Raspberry Pi Pico, to mount it onto a 4-Channel relay.
The bracket has 3 holes to mount the Pico with M2 bolts. The bolts screw right into the plastic, no threads needed.

I use these setup as a simple watering system for my greenhouse.
