Collect a whole class’s SVGs on one link, catch the broken files before they reach the cutter, and pack every student’s work onto a single sheet. Plus the generators you would otherwise draw by hand — boxes, living hinges, gears, kerf tests and outlined text. Everything runs in the browser on a school network, with no software to install.
Students upload SVGs to a class link. Pack them onto a sheet, download SVG or DXF with Cut and Engrave layers.
Sign in to create a class →Convert a JPG, PNG, or BMP into a 1-bit black-and-white BMP for laser engraving. Threshold, dither, brightness, and contrast — all in your browser.
Open engrave tool →Type in W × D × H and material thickness, get a 6-panel finger-jointed box ready to laser cut. Download as SVG or DXF.
Open box maker →Generate a small calibration sheet — a caliper square plus a fit ladder of stepped tabs. Cut once, measure, dial in your laser's actual kerf for press-fit joints.
Open kerf tester →Generate a slit pattern that lets flat ply or acrylic bend around a curve. Tune cut length, link width, and row spacing for your material — download SVG or DXF.
Open living hinge →Type text, pick a font, get a cut/engrave-ready outlined SVG or DXF. Skip the Illustrator/Inkscape detour and the font-installation step on the school machines.
Open text tool →Parametric involute spur gear — set teeth, module, pressure angle, and bore; download SVG or DXF ready to cut. Pitch-circle overlay makes laying out meshing pairs easy.
Open gear generator →Pack multiple STLs onto a print bed and download a single combined STL. Students can upload to a class link too — pack everyone's prints in one job.
Open STL packer →Slice an STL into horizontal cross-sections at your material thickness, pack the layers onto sheets, and download SVG/DXF ready to cut. Labelled layers so you can glue the stack in order.
Open STL slicer →The slow part of laser cutting with a class has never been the cutting. It is the twenty minutes spent collecting files off twenty different accounts, opening each one to find the stray guide line someone left outside the artboard, and then arranging them all on a sheet without wasting half the material.
Give the class one upload link and every file arrives in one place, named by student. Each upload is scanned as it lands: stray elements sitting far outside the drawing are flagged and can be removed in a click, so a file that would have sent the head chasing off to the corner of the bed is fixed before it costs you a sheet of ply. When the class has finished submitting, pack everything onto your material size and export one SVG or DXF with separate Cut and Engrave layers.
Nothing installs and nothing needs admin rights. The generators run entirely in the browser, so they work on locked-down school computers and on student laptops alike, and the files never leave the machine. Fonts are built in, which removes the usual problem of text that looks right in the classroom and reflows on the workshop PC. Exports target DXF R14, the version nearly every laser controller and CAM package still reads cleanly.
Finger-jointed boxes from three dimensions and a thickness, with kerf compensation applied. Living hinges that let flat plywood bend. Involute spur gears for mechanisms projects. A kerf test sheet to measure what your cutter actually removes, so press-fits fit first time. Outlined text without the trip through Illustrator. Image conversion for engraving, and STL slicing for stacked-plywood contour models.
