IKEA Glass Marker

thingiverse

This is a compact marker designed specifically for IKEA POKAL drinking glasses. The marker can be printed in various colors and/or personalized with individuals' initials on its flat surface. Simply place the marker on the edge of the glass, and all confusion about which glass belongs to whom will instantly cease. The inner stairsteps accommodate the significant variation in glass thickness - press the marker firmly until it takes hold, but avoid forcing it all the way down, as this may cause it to shatter. If you're skilled in OpenSCAD and possess a reliable printer, you can also print up to four letters into the flat side of the marker. However, you'll need to manually adjust the kerning settings to achieve optimal results. The code behind this project is not particularly elegant, but it serves its purpose effectively.
