Gridfinity Sets – fits DeWalt TSTAK Drawers/Cases

Gridfinity baseplates and bins for four more TSTAK sizes, each from DeWalt's published interior table: the deep drawer unit, the 2-drawer unit, the flat-top case (and deep box, same floor), and the long-handle case.

Dimensions used (manufacturer-published inner sizes):

• DeWalt support: interior dimensions of TSTAK drawers (L × D × H): https://support.dewalt.com/hc/en-us/articles/360012660578-What-are-the-interior-dimensions-of-DEWALT-Tstak-drawers

How it works: plain Gridfinity baseplate tiles (lightweight, open-bottom, 42 mm standard) butt together, and plain spacer strips fill the gap to the walls, so nothing slides. No glue and no snap clips. Every part fits a 256 × 256 mm bed. Print the fit-test corner first.

Estimated print time and filament (Bambu Studio slicer estimate, A1, PLA, 0.2 mm, 15% infill, 3 walls, no supports):
