Auxetic Grip Pad — Rotating-Squares Metamaterial (parametric, 4 sizes + coupon)
A flat, supportless auxetic grip pad — a sheet of rigid square tiles joined to their neighbours by thin living-hinge necks in a checkerboard, so it has a negative Poisson ratio (nu ~= -1): pull it and it expands on BOTH axes instead of necking in. That makes it go synclastic — drape it over a jar lid or dome and it caps the curve and hugs it instead of wrinkling, so it grips. Bundled at 4 grid sizes (3x3, 6x5, 8x8, 10x10), plus a 3x3 test coupon and the full parametric OpenSCAD source — change the grid, tile pitch, hinge width and thickness and re-render any size you like. Print in PETG or TPU: the necks are living hinges and PLA fatigue-cracks.

AC/DC Socket Plug — EU Child-Safety Blanker
Round disc that fills the recess of a EU Schuko/CEE 7/3 wall socket and blocks both phase holes. Two big spherical finger pockets on the dome let you pry it back out one-handed; a U-slot at one edge wraps around the earth pin so the plug seats flush in grounded sockets. Two-colour print: dark body + yellow lightning-bolt inlay on the dome (AC/DC theme). Ø 38 mm × 19 mm dome.

Adjustable Support — Parametric Two-Piece Screw Jack (1× and 2×)
Two-piece screw jack with a buttress-style helical thread. Spin the post to extend or retract the height. Bundled in two sizes: original (~Ø36, 20 mm travel range) and 2× scale (~Ø72, 40 mm travel range). Parametric OpenSCAD lets you re-render at any scale_factor. Note: the fit is slightly loose — the thread engages cleanly with about 0.5 mm radial slip per side, which makes the spin feel free rather than tight.

Print-in-Place Spring-Gate Carabiner — keychain clip (PETG)
A one-piece print-in-place keychain carabiner. No pin, no separate gate, no spring, no assembly — the body itself is the spring. Push the thin flank inward with your thumb, the gate opens, hook it on, release, it snaps shut. Prints flat with no supports. PETG recommended. NOTE: a light keychain clip for small items only — NOT a safety / climbing / load-bearing carabiner.
