eufyMake E1 jig for metal ballpoint pen 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 52 pockets for metal ballpoint pen blanks, in 26 rows of 2. 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 7.4 mm thick with 5.4 mm deep pockets, each 10.7 mm blank stands 5.3 mm proud of the jig and its top is 12.7 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.
A pen lies in a slot; only a narrow strip along its top is printable flat. Clip and taper vary by model.
Round items like tumblers and pens print or engrave all the way around only on a rotary attachment; this jig holds them for flat work.
