If you have a 3D printer at your school you simply have to get some of these Max Wax pens!!! I have been using mine for a couple of weeks now and I can honestly say it makes it a lot easier to clean up any rough edges, excess sidewalk or clean up a cavity on your 3D prints.
These pens are inexpensive and operate from one AA battery. The tip can heat up to 450 degrees in a matter of minutes. I am certain the Max Wax pen will become an essential makerspace tool for your school too.
