| Part | Cut length | Cut width | Thickness | Qty | Grain |
|---|---|---|---|---|---|
| 325 mm | 50 mm | 9 mm | 2 | Along length | |
| 242 mm | 50 mm | 9 mm | 2 | Along length | |
| 307 mm | 242 mm | 9 mm | 1 | Unrestricted |
Item allowance: 9 × 11 inch abrasive sheets — 279.4 × 228.6 mm, plus 10 mm of handling space per axis.
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.

Put it together
1. Measure and mark
Measure the actual sheet thickness (9 mm in this plan). Mark front / back F, left / right L, base P. Recalculate if the measured thickness differs. Check your abrasive sheet dimensions; manufacturers sell several formats.
Parts: F, L, P · Start here2. Cut and label the parts
Follow the numbered full-width cuts in the cutting sequence, then subdivide each labeled child region. Keep the part IDs and grain arrows. Use the instructions supplied with your tools; this plan is not tool training.
Parts: F, L, P · After measure3. Dry-fit the outer walls
Front and back span 325 mm. Fit the 242 mm side walls between them. Check the outside footprint 325 × 260 mm and square the corners. The inset base is 307 × 242 mm; its underside sits flush with the wall bottoms. Total base clearance is 0 mm per axis (0 mm on each side).
Parts: F, L, P · After cut4. Assemble the base and walls
Prepare and bond the butt-joint contact faces using an adhesive suitable for your sheet. Center the inset base at z = 0 mm. Check squareness before clamping. For a clearance gap, verify the adhesive allows that gap; use zero clearance or revise the fit if it does not.
Parts: F, L, P · After dry-fit5. Cure, finish and check the fit
Follow the adhesive manufacturer's cure and handling instructions. Smooth edges and apply a finish compatible with your materials. Attach four self-adhesive felt pads under the base corners. Store by grit using loose paper separators. Keep dusty abrasives away from electronics. Use for light desktop items; no load rating is provided.
Parts: F, L, P · After glue
