L-shaped shelf bracket, 150 mm reach
A simple right-angle bracket for a light shelf up to about 150 mm deep, holding books, small speakers or plants in a hallway. Good geometry uses a 6 mm thick vertical leg of 150 mm, a 140 mm horizontal leg, a 45-degree gusset connecting both and three 5 mm holes per leg. Print it on its side so layers run along the legs, and give the inside corner a generous 8 mm fillet where load concentrates.

Fit notes
Store-bought brackets come in a handful of sizes; a generated one matches the exact shelf depth and screw spacing of your wall. Describe reach, thickness and hole layout, look at the preview, then ask for a stronger gusset or shorter leg in plain English.

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.
