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. Coming soon.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 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
