Tube reducer sleeve, 25 mm to 22 mm
A stepped sleeve that lets a 22 mm tube plug into the end of a 25 mm tube, useful for extending a curtain pole, joining two lengths of aluminium tubing or fitting a smaller foot onto a larger leg. The outer section is 24.8 mm in diameter with four compression slots so it presses into the 25 mm tube with light friction, and the inner bore is 22.2 mm to accept the smaller tube. A 3 mm web separates the tubes and a shoulder ring keeps the sleeve from disappearing inside. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer?

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.
