Voron 2.4 belt tension gauge and idler spacing card
A credit card sized gauge for tuning a Voron 2.4, Trident or 0.2 build: one edge is a 110 Hz reference comb for checking AB belt tension by plucking, the other has stepped notches for 6 mm GT2 belt, the 2020 extrusion slot and the 3 mm gap between XY idler stacks. The card is 85 by 54 mm and 3 mm thick with 0.6 mm embossed labels, a 5 mm lanyard hole and a 45 degree edge so it slides between belt runs; each notch is cut 0.1 mm oversize for a snug reference. Print it flat in PETG at 0.16 mm layers so the small features stay crisp. 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
Model a gauge card 85 mm long, 54 mm wide and 3 mm thick with a 6.1 mm belt notch 10 mm deep, a 6.2 mm extrusion slot key, a 3.1 mm feeler tab 15 mm long, a 5 mm lanyard hole, 0.6 mm embossed labels for each feature and a 45 degree chamfer along one long edge.
Fit notes
Voron docs quote tension by frequency, and a downloaded card may not match your belt path length. In SpeakCAD you give your gantry size and belt lengths, preview the card in the browser, add a Z belt notch in the chat, and 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.
