Inspired by the Drybox humidity sensor mount by RobMagus (link is under original model) I created a mount which is better fitting for metric nuts and bolts.

The mount holds a cheap LCD temperature / humidity sensor and can be attached to a transparent storage box by drilling 4 small holes.

For mounting also needed:
4 pcs. M3x10 button head screws (socket head screws also work)
4 pcs. M3 nuts or nylon nuts
