Magnet Label Holder

A simple blank square with 3mm holes in the back for magnets that I can use to affix printed labels from my Nelko label maker and be able to move them around without the need to print a new label. Help me keep my filament shelves much for organized! I recommend using a drop of superglue in the hole before putting in the magnets but it does fit snug enough that you can use it without. (I am not liable for the loss of any magnets that may fall out due to not using a drop of glue.) Dimensions: 45mm x 19mm x 13mm with 3mm diameter holes on the back side.Materials: 2.20g of PLA & 2, 3mm x 2mm magnets, and a drop of superglue (optional).Print time: 12m 12s for one.
