Compost aerator tool head
A compost heap breaks down faster when air gets into the middle, and this aerator head turns a broom handle into a plunging turner. The head is a 60 mm diameter hub with a 25 mm socket for a wooden handle, secured by two screw holes, and four 60 mm wings that fold flat on the down-stroke and spread on the pull, each hinged on a 4 mm pin with a stop tab. Print the hub upright in PETG or ASA with 5 walls, and the wings on their sides at 100 percent infill.

Example prompt
Design a compost aerator head: a 60 mm diameter hub 70 mm tall with a 25.5 mm socket 50 mm deep and two 5 mm screw holes, and four hinged wings 60 x 25 x 5 mm on 4 mm pins that fold up 90 degrees and stop near horizontal.

SpeakCAD builds the socket to your handle diameter and scales the wings for a small tumbler or a large bay. If you prefer a fixed corkscrew head, describe it and the model regenerates in the chat.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.
Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
