Glowforge Pro / Plus / Basic jig for 4 in square coaster blanks
With 0.2 mm clearance per side, 4 mm webs and a 8 mm margin, the Glowforge Pro / Plus / Basic's 495 × 279 mm work area fits 8 pockets for 4 in square coaster blanks, in 2 rows of 4. Staggering the rows does not help with this shape, so the grid is the best layout.

What to know before you cut
The 0.2 mm starting clearance assumes a laser-cut acrylic, MDF or plywood jig. Cut the test-fit coupon (0.0 to 0.5 mm) in the generator before the full plate: blanks from different suppliers vary, and the laser's kerf makes cut holes slightly larger than drawn.
As a laser-cut 3 mm sheet with through-holes, the blanks rest on the bed or honeycomb and stand 0.18 mm above the sheet.
Cut the jig and leave the sheet on the bed: the pockets are then exactly where the machine thinks they are. The cut file has 4.76 m of cut path on a 495 × 279 mm sheet, with row letters and column numbers engraved in the margin.
The 3 mm corner radius is an estimate; measure one blank and adjust it in the generator if the corners bind.
