Mimaki UJF-3042 MkII e jig for iPhone 17 case blanks
With 0.3 mm clearance per side, 4 mm webs and a 10 mm margin, the Mimaki UJF-3042 MkII e's 300 × 420 mm work area fits 6 pockets for iPhone 17 case blanks, in 2 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 8 mm thick with 6 mm deep pockets, each 12 mm blank stands 6 mm proud of the jig and its top is 14 mm above the bed, within the 153 mm the Mimaki UJF-3042 MkII e accepts.
The full 300 × 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.
Apple lists the phone at 71.5 × 149.6 × 7.95 mm; the case adds an amount that varies by model. Measure your case.
The 13 mm corner radius is an estimate; measure one blank and adjust it in the generator if the corners bind.
