SIM eject tool and nano SIM card holder keychain
A keychain tag that stores a SIM eject pin and up to two spare nano SIM cards (12.3 x 8.8 x 0.67 mm) for travel, so swapping an eSIM-less iPhone 15 or Galaxy S24 to a local carrier does not mean hunting for a paper clip. The eject pin sits in a 1 mm bore with a friction lip, the SIM pockets are 12.6 x 9.1 x 0.9 mm behind a sliding cover, and a 5 mm ring hole takes a split ring. The tag is 40 x 22 x 5 mm, prints flat and needs no supports. 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.Adjust

Example prompt
Design a 40 x 22 x 5 mm keychain tag with a 1 mm diameter, 22 mm deep bore for a SIM eject pin with a friction lip, two 12.6 x 9.1 x 0.9 mm nano SIM pockets under a sliding cover on 0.8 mm rails, a 5 mm split ring hole and 1.2 mm walls.
Fit notes
Nano SIM pockets have to be tight or the cards fall out in your pocket. In SpeakCAD you say how many cards and which pin you carry, preview the tag in the browser, add a slot for an adapter or a microSD in the chat, then download the STL.

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.
