Saddle clamp for 20 mm electrical conduit
A single-screw saddle that fixes 20 mm PVC electrical conduit to a wall or joist, handy when a run needs one more clip and the shop is closed. The arch has a 20.4 mm inner diameter so the conduit presses in with light resistance, a 3.5 mm wall, a 16 mm width and a central 4.5 mm screw hole in a raised boss between the two feet. Half-height feet let the conduit sit flat against the surface, and a chamfer at the mouth eases insertion.

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.
