Microphone stand thread adapter, 3/8 to 5/8 inch
A threaded bushing that lets a European 3/8 inch microphone stand accept a US 5/8 inch 27 TPI clip or shock mount. The part has an external 5/8-27 thread about 12 mm long, an internal 3/8-16 thread through a 15 mm body and a 22 mm knurled flange for finger tightening. Printed threads work well at this pitch when modelled with 0.15 mm radial clearance and a small lead-in chamfer; printing the adapter standing on its flange keeps the thread profile clean and strong.

Example prompt
Create a thread adapter bushing: external 5/8 inch 27 TPI thread 12 mm long with 0.15 mm clearance and a 0.5 mm lead-in chamfer, internal 3/8 inch 16 TPI thread through a 15 mm long body. Knurled flange 22 mm diameter, 4 mm thick between the two sections.
Fit notes
SpeakCAD models both threads to the exact standard and clearance you request, so you are not relying on a file drawn for a different printer's tolerances. Preview in your browser, then ask for a 1/4 inch variant or a longer flange if the first fit is not to your liking.

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.
