What is OmArTronics 3D Kollektion?

OmArTronics 3D Kollektion is a free, browser-based collection of print generators from the maker behind the OmArTronics YouTube channel. Its soundwave tool is the stand-out for gifts: load an audio file (MP3, M4A, WAV, OGG or FLAC, up to 3 minutes) such as a voice message, a favorite song or a recorded heartbeat, and it turns the waveform into a printable plate.

You can pick a rectangle, circle, hexagon or heart plate, lay the bars out in a line, mirrored or in a circle, change bar shape, count and height, add text and a heart, and include a mounting plate. Export is STL, or 3MF with multi-color layers, and you can save your own presets.

The same site also generates lithophane lamps, portrait reliefs, string art, parametric lamps, vases, planters, boxes, 3D text and maps, all free and without an account. Its license says the models you generate are yours to use, personally or commercially. It is less known than the big platforms, but the soundwave tool fills a gap that few other generators cover.
