Do you use more than just PLA? Want to remember to apply gluestick when needed, select the right temperatures? I use grandmas-favorite-filament-clip (closed variant) - and use different colors for each material so I get a reminder what settings are needed, as I load a spool.
Chamfered holes allow mounting with one or more screws - or to push clips out if you change your mind on colors.
Print with one color change for the text. Made to hold https://www.printables.com/model/24371-grandmas-favorite-filament-clip (classic or closed).
