Festool Domino DF 500 offset spacer set for shelf joints
A set of stepped spacers that sit under the fence of a Festool Domino DF 500 so mortises land at a fixed offset from the edge for shelf pins, drawer dividers and offset frame joints. Each spacer is 120 mm wide to span the fence, 30 mm deep with a 5 mm lip that hooks the fence's front face, and comes in 5, 10, 15 and 20 mm thicknesses labelled with 0.6 mm embossed digits. A 6 mm slot accepts the DF 500 stop pins so the spacer registers repeatably. Print in PETG or ASA at 100 percent infill with the label face up, since a soft spacer wrecks the accuracy.

Example prompt
Design a fence spacer 120 mm wide, 30 mm deep and 10 mm thick with a 5 mm tall and 3 mm thick lip along the front edge, two 6 mm slots 40 mm apart for stop pins, 0.6 mm embossed thickness digits on top, and 1 mm chamfers on all edges, plus 5, 15 and 20 mm variants.
Fit notes
Festool's own offset system is expensive and only covers set steps. In SpeakCAD you list the offsets your project needs, preview the stack in the browser, add a 12 mm or 32 mm spacer in the chat, and download the STL for all four at once.

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.
