Dremel 4000 plunge router base with depth stop
A small router base that threads onto the nose of a Dremel 4000, 3000 or 8220 so the tool can cut inlays, dados and hinge recesses with a 3.2 mm shank bit. The Dremel nose has a 3/4 inch 12 TPI thread (about 19 mm), so the base carries a matching modelled thread 10 mm long, two 8 mm guide posts 60 mm apart, and a 90 by 90 mm sole with a 20 mm centre opening and a 45 degree bevelled edge for visibility. Depth is set by an M4 thumbscrew clamping a sliding collar; print the sole flat in PETG with 4 perimeters, and the threaded collar upright at 0.12 mm layers.

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.
