Downspout splash diverter
A downspout that empties straight onto the soil erodes a hole and splashes the wall. This diverter slides over a 65 mm round downspout end and spreads the flow across a 250 mm wide fan with low ribs that break up the stream. It is 200 mm long with 3 mm walls, an interference collar with a screw hole for security, and a 5 degree slope to keep water moving. Print it collar-down in ASA or PETG, which shrug off UV and frost.

Downspout profiles differ by house, and SpeakCAD sizes the collar to yours so it stays on in a storm. Extend the fan, add a hinge so it lifts for mowing, or request a rain-barrel diverter variant, all in the same conversation. Preview in your browser.

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.
