A feasible cutting layout

Numbered cuts span their parent region. Coordinates use the sheet's top-left origin. Trim all four edges of each sheet you use first. Keep unused sheets whole. This layout does not claim the lowest possible material use.

Compare your stock choices

Try this same inventory with offcuts first and standard sheets first. Each result is a feasible estimate; the solver may miss a better layout.

Connections and machining

Sliding lid · 12 pieces · 12 mm plywood, 6 mm lid. Lower support rails and upper guide rails form two side channels. Slide the lid from the low front wall toward the rear stop. Pull the front tab Q to reopen it.

No grooves or notches are required. Cut the rectangular parts, then follow the connection details.

Put it together

Done
1. Measure and mark
Measure 12 mm main plywood and 6 mm lid plywood. Mark every part and its grain direction; recalculate before cutting if either thickness changes. Measure the protected tools and all closed cases as a packed kit, including the lid clearance.
Parts: F, B, L, P, R, U, S, T, Q · Start here
Done
2. Cut and label the blanks
Follow the rectangular cutting map and label every instance. Machine the separate notches or grooves only after the blanks are cut. Follow the tool manufacturer’s setup and workholding instructions.
Parts: F, B, L, P, R, U, S, T, Q · After measure
Done
3. Dry-fit the case
Check the 300 × 220 mm footprint, square corners and centered inset base. Base clearance is 0 mm per edge; confirm the selected adhesive can bridge that gap.
Parts: F, B, L, P, R, U, S, T, Q · After cut
Done
4. Assemble the base and walls
Bond the base and wall contact faces, keeping the base underside flush with the wall bottoms. Clamp square and follow the adhesive cure instructions.
Parts: F, B, L, P · After dry-fit
Done
5. Set the lower and upper rails
Bond R at z = 69.7 mm. Fit U flush with the side tops using a 6.3 mm spacer above R. Remove spacers and clear glue squeeze-out.
Parts: R, U, L · After glue
Done
6. Fit the rear stop
Bond S against the back, between the side rails, with its underside at z = 81.7 mm. Keep the front entry unobstructed.
Parts: S, B · After rails
Done
7. Add the lid pull
Bond the 40 × 12 mm pull tab on top of the lid, centered across its width and flush with its front edge. Let the joint cure before using the pull.
Parts: Q, T · After cut
Done
8. Slide and check the lid
Insert T from the front. Check 0.15 mm clearance at each side and above and below, free travel to the rear stop, and full forward removal using Q. Keep the lid unglued to its rails.
Parts: T, Q, R, U, S · After stop, pull
Done
9. Cure, finish and check the fit
Follow the adhesive cure instructions. Smooth edges, test the intended objects and apply a compatible finish without filling the clearances. Fit four felt pads. Use only for light desktop items; no load rating is provided. Use separate closed cases for sharp items. The sliding cover has no lock or child-safety rating.
Parts: F, B, L, P, R, U, S, T, Q · After slide
