Pick one of 14 patterns or upload your own SVG or photo and get a printable texture roller: the pattern wraps seamlessly around the cylinder, raised or engraved. Set the diameter, length, axle bore, repeats around and along, spacing, scale, brick stagger and pattern depth. An optional fork handle prints as a separate part — push a dowel through the bore and the roller spins. Prints upright on its end. Runs in the browser, no CAD.

Turn text, an SVG logo or a photo into a printable stamp: a raised relief on a rounded, sharp-cornered or round block, mirrored for a correct imprint, plus a mushroom knob that plugs into a socket in the back and prints as a separate part. Pick from nine fonts and set letter height, padding, block size and relief height. Works for clay, wax or ink. Runs in the browser, no CAD.

Type a word or upload an SVG and get a printable frame for a faux stained glass suncatcher: the design is cut through as open windows you seal on the back and fill with tinted resin. Letter centers and floating islands are held by thin auto-bridges, and a hanging ring can sit outside the frame or be built into it — one or two, top or sides. Set the size, lead width and thickness; it prints in one color. Runs in the browser, no CAD.
