Keycap storage tray with stem posts
A tray for sorting and storing loose MX-style keycaps on a grid of cross-shaped posts that hold each cap upright and prevent scuffing. Posts are 4 mm cross stems with a 0.15 mm undersize so caps press on gently, spaced 19.05 mm apart to match keyboard layout. Walls are 2 mm, the floor is 3 mm, and a snap-fit lid with 0.3 mm clearance keeps dust out so trays can stack. 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.Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer?

Example prompt
Design a keycap storage tray with a grid of 12 by 6 MX cross stems 4 mm at 19.05 mm pitch, 0.15 mm undersize, plus one 2u and one 6.25u stem pair along the bottom row, 2 mm walls, 3 mm floor, snap-fit lid with 0.3 mm clearance.
Fit notes
Sets with novelties, spacebars and extra rows do not fit a fixed grid, so describe your set to SpeakCAD and it lays out posts for every cap size including 2u and 6.25u. Preview the tray in the browser, tweak the stem fit if your caps are looser or tighter, and download the STL once it matches your collection.

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.
