HC-SR04 and nano

thingiverse

I designed this rugged enclosure for a HC-SR04 distance sensor paired with an Arduino Nano, aiming for an industrial look. It also accommodates a compact DC-DC converter from eBay; if you opt for the LM2596 instead, it will fit as well but requires glue to secure in place using silicone blobs. Similarly, the HC-SR04 might benefit from being glued in position. To assemble and utilize this clamp, you'll need (2) 8-32 or 10-32 screws that are 3 inches long. Due to a lack of a reliable method for securing the back cover, I added two holes near it; slip a wire tie through these openings and fasten the cover with it. Maintain the parts' orientation as they were when you printed them. The housing and cover are angled at 45 degrees relative to the print bed, so your printer's diagonal printing will result in a straight face on the housing when completed.
