UPDATE 03/27/2026: Added a STEP file that includes all bases and inserts, making it easier for anyone to adapt the design for soldering pens that I don't have on hand.

Just uploaded a modular stand for USB-C soldering irons. I designed it with swappable inserts, so if you switch irons later, you don't have to print a whole new base. There are a few base options too. Currently, I’ve verified and uploaded inserts for the FNIRSI HS-02B, Miniware TS21, and ANENG SL108. Make sure to use heat-resistant filament for the inserts. 🔥
