Shure SM7B to 3/8 inch mic arm adapter

A threaded adapter that lets a Shure SM7B or SM7dB yoke, which has a 5/8-27 female thread, screw onto a boom arm that only offers a 3/8-16 male stud, such as a Rode PSA1 or a cheap desk arm whose brass insert went missing. The part is a 22 mm diameter, 18 mm tall knurled cylinder with a 3/8-16 female bore 12 mm deep and a 5/8-27 male stud 10 mm long on top, both with 0.15 mm thread clearance so they bite without stripping. Print it standing up at 0.12 mm layers in PETG or ASA for the 765 g microphone; the knurling gives you grip when tightening.

Printed threads only work when the pitch and clearance are tuned to your printer, which a random download cannot know. In SpeakCAD you type the two threads and your nozzle size, preview the adapter in the browser without paying, ask for a 1/4-20 version for a Shure MV7 in the chat and download the STL.

Create a microphone thread adapter 22 mm in diameter and 18 mm tall with a 3/8-16 female thread 12 mm deep at the bottom, a 5/8-27 male thread 10 mm long on top, 0.15 mm thread clearance, a 2 mm knurled grip band and a solid 4 mm centre web, for a Shure SM7B on a 3/8 inch arm.

Change any number to match what you measured. The AI keeps the rest of the design consistent, and small follow-up edits after a download are free.
