Calendar holder / Calendar clamp

For some odd reason, I always have calendars rip and fall off the wall in the middle of the night or during an important Zoom meeting. I thought  “there should be a tool that fixes this” and searched for hours (like 3 minutes) and then crafted and beta tested this until it finally worked decent enough to provide to the masses ( aka you). 

This invention has three parts- the back, the front, and the nut. You clamp the calendar between the back and the front parts and use the nut to squeeze them together forcing the calendar to delicately hang there without falling. Depending on your printer tolerances, you may need to use an M5x0.8 tap and die to clean up the threads (pretty tight modeling tolerances).

Voila, no more calendar disturbing your beauty rest!
