Adapter plate to remount a PCB on a different hole pattern
A thin intermediate plate that lets a circuit board with one set of mounting holes attach to an enclosure or chassis drilled for another. The plate is 3 mm thick with a footprint 10 mm larger than the board, four 2.5 mm tall standoffs with M2.5 holes matching the PCB, and four countersunk 3.5 mm holes matching the chassis. Cut-outs under tall components and a 5 mm cable slot keep it light, while 2 mm fillets on the corners avoid sharp edges in the case. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer?

Example prompt
Design a PCB adapter plate 100x75x3 mm with 2 mm corner fillets. Four standoffs 2.5 mm tall, 5 mm diameter with 2.2 mm holes at 90x65 mm spacing for the board. Four 3.5 mm countersunk holes at 80x50 mm for the chassis. 5x20 mm cable slot on one edge.
Fit notes
Both hole patterns are numbers you already have, and SpeakCAD places every standoff and screw hole where you say, checking they do not overlap. Preview in the browser, then ask for taller standoffs, heat-set insert pockets or a second board position in the chat.

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.
