Adjustable support bracket for a sagging graphics card
A telescoping pillar that stands on the PC case floor or power supply shroud and props up the far end of a heavy graphics card so it stops drooping in the PCIe slot. It has a wide 40 x 40 mm base, an outer column with an inner sliding post adjusted by an M4 thumbscrew through a slot, and a padded 25 mm wide saddle on top that rests under the card's backplate or heatsink. Height range of 60 to 100 mm covers most cases, and 3 mm walls keep it rigid. 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?

The gap between your card and the shroud is a number only you can measure, and SpeakCAD builds the bracket around it. Preview in the browser, then ask for a wider saddle, a magnet pocket in the base or a fixed-height version that needs no screw.

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.
