Description
A five-point star cookie cutter, 60 mm tip to tip, with 18 mm tall walls and a wide flat flange around the top edge. The flange gives a thumb a broad surface to press on, so pushing the cutter through dough doesn't put a thin edge against your skin.
The values below are the ones worth changing. Everything else follows from them.
R, 30 mm): This is the tip radius, so 60 mm across. Change it to scale the star. At about 40 mm across or less, check that the flange doesn't crowd the inner corners.ratio, 0.5): This is the inner radius divided by the outer radius. Lower values like 0.4 give spikier points. Higher values like 0.6 give a chubbier, more rounded star. Very spiky points are harder to press out of dough.flange_w 4 mm, flange_t 2 mm): Widen it for a more comfortable press, or thicken it for more stiffness. Rounding the flange's outer corners is an easy variant if you want it softer on the thumb.wall, 1.2 mm): This is about three nozzle widths on a 0.4 mm nozzle. Thinner cuts more cleanly but is more fragile. Thicker is sturdier but pushes dough aside more.H, 18 mm): Lower it for thin cookies, or raise it for thick dough or a deeper grip.R and nothing else.Print it flange-up or flange-down on the bed. Flange-down needs no supports, and the thin walls grow straight up from the flange. Use food-safe filament if you want to use it on dough.

A cookie cutter echoing the wallpaper clouds from Andy's room: a big bump on the upper left, smaller puffs along the top and a long flat base. The centre is open so dough passes straight through. 15 mm tall wall, about 1.2 mm thick, thin clean cutting edge on the flat bottom Widened rim at the top for pressing by hand About 100 mm wide, prints flat with no supports
Softflow is a screw-on splash diffuser for faucets with an M22x1 male outlet thread. The base is perforated with a staggered hex grid of small holes, breaking the flow into many fine streams for a softer, wider spray. A short open chamber between the thread and the perforated floor lets water spread across the whole hole pattern before it exits. Features M22x1 female thread, 8 mm deep, with a beveled lead-in at the opening Staggered hex grid of 1.5 mm holes at 2.6 mm spacing, inside an 18 mm circle 3 mm perforated floor with a relief chamber above it Chamfered top and bottom edges on a round body Dimensions Outer diameter: 28 mm Overall height: 16 mm Thread: M22 x 1 mm pitch, 8 mm engagement depth Floor thickness: 3 mm Print notes Print with the perforated face down on the bed, opening facing up; no supports are needed. Thread fit has not been tested against a real faucet. If it binds, increase the thread clearance slightly. A fine layer height (0.12–0.16 mm) keeps the small holes and thread crisp. PETG or ASA suits wet, warm-water use better than PLA.
A bowl that skids across the counter or tips the moment you stir it is the annoyance; this one has an almost square base that keeps it planted. The base is a 70 mm square with rounded corners, so it sits flat instead of rocking, and the walls flare out to a 120 mm rim that is rounder and easier to eat from. What decides the fit Base footprint: 70 mm rounded square — the number to check against your shelf, tray or cupboard. Rim: 120 mm across at the widest point. Height: 50.8 mm (2 in). Walls and floor: 3 mm thick, so it holds its shape without being heavy. It prints as one piece, standing on its flat base, so no supports are needed and the inside comes out clean.

A freestanding stand that holds a freezer or piping bag open so both hands are free for filling. The bag mouth is pulled through a 120 mm inside-diameter ring, folded over the outside, and secured with a separate split clip that grips the folded rim all the way round. The base is a wide 270 × 250 mm plate with a rear post, so the stand resists tipping when a bag is loaded. The ring sits at the top of the post, 165 mm above the plate, with a flared lip to keep the fold from slipping off. Ring: 120 mm inside diameter, 40 mm tall, on a short arm off the post Base: 270 × 250 mm, 8 mm thick, chamfered edges, with a gusset on the post Clip: split spring ring, 24 mm tall, with finger tabs for opening Parts: base with post, ring, and clip are colour-labelled; the clip prints separately Material: PETG suggested for the clip so it keeps its spring To use, pull the bag mouth up through the ring, fold it down over the outside, then snap the clip over the fold. The ring height suits bags up to roughly 165 mm long; longer bags will rest on the base. The clip's grip has not been test-printed, so the gap may need adjusting for thicker or thinner bag film.

A taco stand that holds three shells upright and open-side up, so fillings stay in place while you load them. The base is a flat 180 × 120 mm block with rounded corners. Three curved slots are cut into it, each one cradling a single shell. Four round feet lift the base off the table. Each slot arcs along its length, which follows the curve of a folded shell. Three curved slots, each 90 mm long and 20 mm wide Slots spaced 55 mm apart across the 180 mm base Base 22 mm thick, with the slot floor 6 mm above the underside of the block Four round feet, 5 mm tall, with chamfered edges Rounded vertical corners on the base Prints flat on its feet, with no supports needed If your shells are wider than 20 mm, widen the slots before printing. Food-safe filament such as PETG is a sensible choice, and a wipe-down after use keeps it clean.
A round plug-style lid for a container with a roughly 94 mm inside diameter. A 100 mm flange rests on the rim and an 8 mm deep, 93.4 mm plug drops into the bore. Fitment Fits: round containers with a bore near 94 mm. Does not fit: bores under 93.4 mm, or slip-over use on a rim. Measure before printing: the container's inside diameter. The plug is 93.4 mm, so a 94 mm bore leaves 0.3 mm per side. Details: the underside is hollowed to 87 mm, leaving a 3 mm flange top and a 3.2 mm plug wall. Overall height: 11 mm.
