Garmin Edge 1040 silicone-style bumper case
A flexible bumper printed in TPU that wraps the Garmin Edge 1040 and 1040 Solar (59.3 x 117.6 x 20 mm) to protect the corners in a crash and the screen edge from the bar bag zipper. The shell is 1.5 mm thick with 0.3 mm clearance, cutouts for the three side buttons and the USB-C port, a 3 mm raised lip around the screen, and the quarter-turn tabs left fully clear so the unit still mounts normally. Print it screen-side down in TPU 95A at 0.2 mm layers with slow outer walls.

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.
