Sharpie Magnetic Holder

To label the food people put in our shared fridge, I made a magnetic sharpie holder.

Parts:

PLA filament
A 1"x1/2"x1/8" magnet with countersunk holes (https://www.kjmagnetics.com/proddetail.asp?prod=BX082CS-S&cat=19)
\#6-32 heat set inserts (https://www.mcmaster.com/94459A280/)
\#6-32 x 1/4" countersunk screws (https://www.mcmaster.com/91099A205/ – or just cut down some longer screws like I did)
A standard Sharpie marker.
