Storage units

The things you build with.

Cases18 sizes · The structural shell everything else builds around - drawers slide in, QuickLocks join case to case, and rails, covers, and brackets grip the same dovetails. Depth-sized parts match the case's collection; universal parts are shared across collections.FREE Classic Drawers18 sizes · The simplest drawer - prints in one piece with the grip built in, nothing to assemble, nothing to buy. Slides into any case of the same collection.FREE Decor Drawers18 sizes · The customizable drawer - the front takes a swappable universal faceplate, so the look changes without reprinting the box. Fits any case of the same collection.FREE Gridfinity Decor Drawers12 sizes · A Decor drawer with a Gridfinity grid in its floor - 42 mm cells, a half-grid channel down the right side, optional 6×2mm magnet slots, and a tear-away front. Same outside size as the Decor drawer, so it takes the same case and the same faceplates.FREE Shelf Inserts4 sizes · A width-sized deck that drops into a case and turns the bay into an open shelf - the same case, no drawer. Fits any case of its width in the collection, including bays raised on Case Extenders; the front edge takes an optional Shelf Lip.FREE Side Covers5 sizes · A clip-on panel for the outer side wall of a case. Hook it in, slide it down, and the ribs and windows of the wall disappear behind one clean face. One cover per exposed side wall, any width, matched to the height it covers: one case, or one taller cover across stacked cases (a 2H cover over two 1H cases) for a seamless side. Prints face-down in one color, or two with the included 3MF (a thin Face over an everyday Core). Fits v2602 and newer cases, which is every case here. Sized per collection.FREE Case Extenders4 sizes · Height spacers for a case opening - stack them for taller open bays, and to raise a bay that takes a Shelf Insert. Sized per collection.FREE

Mounting

What holds a build together · auto-added by the Planner when your layout needs them.

Covers4 sizes · The cap of a tabletop build - the lower cover carries the drawer stoppers and dovetails, the upper locks the layer, and staggered seams tie the sections into one rigid block. Sized per collection.FREE Foot Rails4 sizes · The base of a tabletop build - two interlocking layers tie the bottom row together when that row is more than one case wide. Sized per collection.FREE Under-Table Rails4 sizes · Screw these to the underside of a desk or bench and cases slide straight in - the rail carries its own drawer stops for the top row. Match the rail's depth to the cases sliding directly into it; mounts with wood screws.FREE
