What it makes
A relief, not a sculpture in the round: from the front it reads as the figure in the photo, from the side it is a thick plaque with a rounded edge, like a carved cameo. A true all-round figure from one photo needs models far too big for a web page; this one runs entirely on your machine, and a relief prints beautifully flat on its back with no supports at all.
The cut-out
Press Cut out the subject and a background-removal model does it. Where it is wrong, use the wand (click a colour to add everything like it, with the tolerance slider) and the brushes. The cut-out is tidied for printing: specks and hairs go, the biggest piece is kept, small holes close (the limit is yours), and anything in the bottom tenth is joined straight down to the tab so paws and feet stand on it.
The shape
The edge rolls over with a quarter-circle profile of the radius you set, worked out from the exact distance of every point to the outline. Depth from the model is split into a broad part that lifts the nearer body and a fine part for fur and folds, both fading to nothing at the edge so the outline stays crisp. Underneath is a flat slab. The tab is a 3 mm bar under the feet; the pedestal's slot is that plus the clearance, 5 mm deep.
Printing
Open the 3MF as a project. The figure lies on its back with the face up: print it as placed, 0.12 or 0.16 mm layers for the finest face, six top layers, no ironing on it (the 3MF sets that on the object). The pedestal prints standing, its top ironed. Push the tab into the slot; a drop of glue if you like. A textured plate gives the back a nice matte; a smooth plate a gloss.
Privacy and the network
The only things fetched are the AI library and the two models, from jsDelivr and the Hugging Face hub, the first time; the browser keeps them. The photo is never sent anywhere, and the page works without the models.
