WOBBLE Roly-Poly Snowman - Always Stands Up

Push him over. He always stands back up.

WOBBLE is a roly-poly snowman for your desk, your shelf or the kids' table. Tap his hat and he rocks and wobbles, then settles upright every time. Lay him flat and he springs back up. You don't need glue, weights or supports: the physics is built into the print.

How it works

• The base is printed at 100% infill. That is about 110 g of ballast, low in the ball.

• Everything above it is printed at 3% gyroid, under 40 g in total.

• The centre of mass sits 3 mm below the centre of the 72 mm ball. Any tilt lifts it, so gravity rolls him back. He has exactly one resting position: upright.

• A small pocket hidden inside the base balances the scarf knot and holly, so he rests dead straight.

We checked this with a mass model calibrated to the slicer's real part weights, not just a guess.

Details

• Knitted hat with ribbed cuff, a fluffy pompom and a holly sprig.

• A knitted scarf with fringed tails, one hanging down his front and one down his back.

• Twig arms, a carrot nose, rosy cheeks, shiny eyes with highlights, and coal buttons.

• 115 mm tall, 148 g.

No glue

Base and body screw together. A keyed pin holds the head facing forward. The head clamps the scarf, and the scarf holds the arms. The face parts snap into undercut pockets.

Files

• Kit, no AMS (recommended): one plate per colour, 8 plates, 4 h 33 min, 148 g.

• Multicolour AMS: 3 plates with the face, buttons and pompom printed in, up to 4 colours per plate.

• 0.2 mm nozzle detail parts: the face and small parts at 0.12 mm layers.

• STLs for both versions, already in print orientation.

The one rule: print the base at 100% and the rest light. The 3MFs already have this set per part. If you slice the STLs yourself, keep the upper parts at 3–10% infill and 2 walls, or he will lean and wobble sluggishly.

Print settings (add to the description)

• Base: 100% infill. This is the ballast.

• Body, head, hat, scarf, pompom: 3% gyroid, 2 walls, 5 top and 3 bottom layers. Hat: 6% and 6 top layers.

• 0.16 mm layers, PLA, no supports. Every STL is already in print orientation.

• Don't go above 10% infill on the upper parts, or he leans and wobbles sluggishly.

NEW - Bambu Lab H3C: WOBBLE_Snowman_H3C.3mf puts each colour on its own PrintTool (almost no purge), re-centred on the 330 x 320 mm H3C plate, with the official H3C machine G-code. Sliced in Bambu Studio 2.09.
