Pole mount bracket for a 40 mm mast
A two-piece clamp that grips a 40 mm round mast and offers a flat face with screw holes for a small antenna or outdoor Wi-Fi unit. Each half is a semicircle with a 40.5 mm inner diameter and 6 mm wall, joined by two M6 bolts through 6.5 mm holes on flanges either side. One half carries a 60 x 80 mm mounting face with four 4.5 mm holes. Printing with the flat face down and using PETG or ASA keeps it stiff and weather-resistant.

Example prompt
Create a two-piece pole clamp for a 40 mm mast. Each half: inner diameter 40.5 mm, 6 mm wall, 50 mm tall, flanges with two 6.5 mm bolt holes. One half carries a plate 60x80x5 mm with four 4.5 mm holes at 50x70 mm spacing. 2 mm flange fillets.
Fit notes
Mast diameters and device hole patterns are rarely standard, so SpeakCAD lets you specify both and generates a clamp that lines up first time. Preview it in the browser, request a wider mounting face or a tilt wedge in the chat, and download when you are happy with the fit.

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.
