Print, push the two parts together with a firm grip until they snap in and then use simple double-sided tape to glue to desired drawer, cabinet door or other appropriate place.

Once in place, you can insert/remove/replace paper labels as necessary

Pre-made STL files in two sizes:

70x50

102x64 (appropriate for inserting a business-card-sized label in it)

Other sizes can be easily made by re-creating stl from openscad while modifying parameter $width and $height (outer size in mm). For significantly smaller/larger sizes you may wish also to change $frame_width for thinner/thicker frame

Recommended print settings: PLA, 0.4mm nozzle, 0.2 mm layer
