# Pocketplate

> Free jig generator for UV printers and lasers: enter a blank size, pick your machine and download a laser-cut SVG, 3MF/STL and an alignment template.

- Pocketplate is a free in-browser jig generator for UV printers, laser engravers and 3D-printed fixtures: enter a blank size, choose a machine, get the maximum number of pockets.
- Outputs: laser-cut SVG (millimetres, 0.025 mm red cut layer, blue engrave layer), DXF R12, 3MF and binary STL (watertight plate with pocket recesses or through-holes), alignment template SVG/PNG with DPI metadata, CSV of pocket centres, test-fit coupon (tolerance ladder).
- Machine presets (35, work areas checked 2026-10-17) include eufyMake E1 (330 × 420 mm), xTool O1 Omni (330 × 420 mm), xTool F2 Ultra UV (a 200 × 200 mm UV galvo laser, not an inkjet), Glowforge Pro (495 × 279 mm) and Mimaki UJF-3042 MkII e (300 × 420 mm).
- Starting clearance per side: about 0.2 mm for laser-cut acrylic or MDF jigs, 0.3 mm for 3D-printed jigs, 0.5 mm or more for natural slate and tile; confirm with a test-fit coupon.
- Example (October 2026): an eufyMake E1 bed holds 40 two-inch round keychains in staggered rows (35 in a straight grid) with 0.3 mm clearance, 4 mm webs and a 10 mm margin.
- Everything runs in the browser; designs and the blank library are stored only in local storage, with a JSON backup. Free during the beta.

## Guides

- [UV printer jig: how to make one that holds every blank](https://jig-generator.pages.dev/guides/uv-printer-jig/): A UV printer jig is a plate with one pocket per blank that puts every piece in the same spot and at the same height, so one artwork file prints a full batch without re-aligning. On the eufyMake E1, all objects on the platform must sit at the same height and a single object may vary by at most 2 mm, so the jig's real job is to make every blank top level and higher than the jig itself.
- [Laser engraving jig: batch keychains and tags](https://jig-generator.pages.dev/guides/laser-engraving-jig/): The most accurate laser engraving jig is one you cut on the laser bed and then never move: the pockets and the engraving share the same machine coordinates, so every blank lands where the artwork expects it. Cut the pockets from cardboard or 3 mm MDF taped to the bed, allow for the kerf (LightBurn's own vernier example measures 0.0575 mm), run the job from absolute coordinates, and frame before each batch.
- [xTool F2 Ultra UV jigs: batch engraving on a 200 mm field](https://jig-generator.pages.dev/guides/xtool-f2-ultra-uv-jig/): The xTool F2 Ultra UV is a 5 W, 355 nm UV galvo laser with a 200 × 200 mm working area, not a UV inkjet printer. With 0.2 mm clearance per side and 3 mm webs, one jig fills that field with 18 dog tags, 6 business cards, or 9 round 2 in keychains in a square grid (12 if the rows are staggered and you use the field right to the edge).
- [Jig clearance per side for laser-cut and 3D-printed pockets](https://jig-generator.pages.dev/guides/jig-clearance-tolerance/): Start laser-cut jig pockets at about 0.2 mm clearance per side (0.4 mm total on each dimension) and 3D-printed pockets at about 0.3 mm per side, then confirm with a tolerance-ladder coupon. Laser kerf makes cut pockets larger than drawn, while printed holes usually come out smaller; Bambu Lab's own calibration example measures a 6 mm hole at 5.66 mm.
- [Best material for jigs: acrylic, MDF, plywood, PLA or PETG](https://jig-generator.pages.dev/guides/best-material-for-jigs/): For most UV-printer and laser jigs, 3 mm cast or extruded acrylic is the best all-round material: it cuts cleanly, stays flat and its glass transition sits at 100-115 °C for ACRYLITE cast sheet. MDF is the cheapest laser-cut option but needs ventilation for its resin fumes. For 3D-printed jigs, PETG (heat deflection 68 °C on the Prusament TDS) has more thermal headroom than PLA (55 °C), and nothing containing PVC should ever go on a laser.
- [Alignment templates for UV printers and lasers](https://jig-generator.pages.dev/guides/alignment-template-uv-printing/): An alignment template is a real-size SVG or PNG of your jig that marks every pocket center, the bleed line and the safe area, so artwork lands on each blank without re-aligning by eye. Import it in millimeters (or as a PNG whose pHYs metadata says 300 DPI, which is 11,811 pixels per meter), lock it to the same origin as the jig, and confirm with one test print on paper or tape before running the batch.
- [Batch personalization workflow for laser and UV shops](https://jig-generator.pages.dev/guides/batch-personalization-workflow/): The fastest way to run personalized orders is to stop working order by order and work plate by plate: group orders by blank, load one jig, merge a names list against numbered pockets, print or engrave the whole plate, then QC and pack in pocket order. On a 330 x 420 mm UV bed that can mean 35 two-inch keychains per run instead of one at a time, with setup time spread over every piece.
- [Laser engraving pricing for batch laser and UV jobs](https://jig-generator.pages.dev/guides/pricing-batch-laser-uv-jobs/): Price a batch job per piece as blank + ink and consumables + machine time + handling labor + (batch setup divided by pieces per batch), add an overhead buffer, then divide by (1 minus your target margin). Setup is the line most shops under-price: in the worked example below, the same keychain costs $9.46 to make as a one-off, $2.81 in a 12-pocket batch and $2.45 in a 30-pocket batch.
- [eufyMake E1 jig: bed size, height limits and batch layouts](https://jig-generator.pages.dev/guides/eufymake-e1-jig/): The eufyMake E1 prints on a 330 x 420 mm (13 x 16.5 in) area, recognizes objects up to 60 mm tall with its camera, prints objects up to 100 mm in flatbed mode and up to 130 mm with Zero-Point Alignment since the July 2026 update, and carries 1.5 kg. With a 10 mm plate margin, 4 mm webs and 0.3 mm clearance, that bed holds 6 four-inch coasters, 35 two-inch keychains, or 48 golf balls by geometry, though for golf balls the load limit is the real ceiling (32 before jig weight).
