Mini Chalkboard

This mini chalkboard is made to display prices or whatever you want really. I suggest PETG if the sign will sit outside in the sun to avoid warping. The chalk board component is just a printed part (included in the 3MF) and spray painted with chalk board paint, though you will likely want to spray prime it first. You can get the paint and primer at any home improvement store or Amazon. The hinge holes are 2mm which is perfect for using a segment of filament to connect the two frame parts. Just melt the ends of the filament so the segment can't back out. In order to keep the two frame sections to opening too far I included a little folding bracket in the 3MF, however I opted to use some tiny chain and screws in order to make it look nicer. The chain and screws are available on Amazon (search for “Antique Bronze Curb Cable Chain Link Necklace Small Width 3mm”). I added NFC tags to the back of mine so people could scan the sign and be taken to my website to save the items for later or
