Logitech MX Master 3S mouse stand with USB-C slot

A parking dock that holds the Logitech MX Master 3S upright at the edge of a desk while it charges, keeping the mouse pad clear. The 3S is 124.9 x 84.3 x 51 mm, so the dock has a 52 x 86 mm contoured pocket 25 mm deep that matches the mouse's flat underside and thumb rest, with 1 mm clearance and a 12 x 8 mm slot at the front where the USB-C cable enters the nose of the mouse. The base is 90 x 70 mm, weighted by a hollow cavity and lined with 2 mm rubber pad recesses. Walls are 3 mm and it prints upright with the pocket facing up. 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? We print this part and ship it to your door. See its priceUpdated

Example prompt

Design a vertical mouse dock for a Logitech MX Master 3S 124.9 x 84.3 x 51 mm with a contoured 52 x 86 mm pocket 25 mm deep and 1 mm clearance, a 12 x 8 mm front USB-C cable slot, a 90 x 70 mm weightable base with 2 mm rubber pad recesses and 3 mm walls.

This prompt comes with the ready-made model when you sign in, in case you want the AI to redesign it (3 credits a redesign); changing numbers in the viewer is free.

Fit notes

Every mouse shell is different, so a dock built from the real profile holds the 3S without rocking. In SpeakCAD you describe the mouse, preview the stand in the browser, adapt it to an MX Master 2S or a Razer Basilisk V3 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.
