Angle grinder cutting guide fence
Straight cuts with a 115 mm angle grinder are hard to freehand, and this guide fence clamps to the workpiece and gives the guard a straight edge to ride along. The fence is a 300 x 40 x 15 mm L profile with a 15 mm rail, two slotted clamp holes and a stepped shoulder so the guard sits 5 mm above the material. Add 3 mm fillets along the rail so the guard glides. Print flat in PETG with 6 walls to survive sparks and pressure; avoid PLA near hot chips.

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.
