eufyMake E1 jig for 3.75 in round cork-back coaster blanks
With 0.3 mm clearance per side, 4 mm webs and a 10 mm margin, the eufyMake UV Printer E1's 330 × 420 mm work area fits 12 pockets for 3.75 in round cork-back coaster blanks, in 4 rows of 3. Staggering the rows does not help with this shape, so the grid is the best layout.

What to know before you cut
The 0.3 mm starting clearance assumes a 3D-printed jig without hole compensation. Cut the test-fit coupon (0.0 to 0.5 mm) in the generator before the full plate: blanks from different suppliers vary, and printed holes usually come out slightly undersize.
As a 3D-printed plate 4 mm thick with 2 mm deep pockets, each 4 mm blank stands 2 mm proud of the jig and its top is 6 mm above the bed, within the 100 mm the eufyMake UV Printer E1 accepts.
The full 330 × 420 mm plate is larger than a 256 mm 3D-printer bed. The 3MF from the generator splits it into 4 tiles along the webs between pockets, so no pocket is cut in half; glue them to a flat backing board and push it into the same corner of the bed each time.
Listed as 1/8 in by one distributor and 0.157 in by another: measure yours and set the pocket depth to match.
