Stackable Keycaps Box (customizable)

Update 19 Dec 2025: Increased distance between the case and lid, so they don't intersect when 12 rows are selected in Customize screen. I own several keycap sets for mechanical keyboards, and none of the existing storage boxes fully met my needs. As a result, I designed my own version, incorporating a few proven ideas from other projects.Customization OptionsThe model is fully customizable, including:Number of rowsNumber of columns (based on 1U keycaps)Internal heightKeycap dimensions (width and length of a 1U keycap)The currently exported model has an internal height of 11 mm, which fits my Cherry-profile keycaps. If you use taller profiles (such as SA), measure your tallest keycap and adjust the InnerHeight parameter using the Customize feature.Design FeaturesTwo dedicated slots for ISO Enter keys, achieved by splitting the last row divider while retaining enough material to securely hold standard keycaps in placeA simple snap-lock mechanism between the partsPrinting NotesWhen im
