Arduino Mega 2560 case
This is not a fixed STL. SpeakCAD generates the arduino mega 2560 case to your millimetres, you adjust it in the chat, then you download and print it.Building the 3D preview…

Adjust
Click a part and change its numbers in the viewer, or ask the AI in the chat: wall thickness, hole size, the thing it clips onto. AI changes use plan credits.3Print
Download a watertight STL or 3MF with a Maker or Pro plan, drop it in your slicer, and print it. Small fit fixes re-download free.

Example prompt
Design an Arduino Mega 2560 case, 103×55×25 mm cavity, 13×12 mm USB-B and 10×11 mm DC openings, four M3 standoffs, header slot in lid, 2 mm walls.
What a arduino mega 2560 case is
A case for an Arduino Mega 2560 R3 (101.5 × 53.3 mm). The cavity is 103 × 55 × 25 mm with a 13 × 12 mm USB-B opening, a 10 × 11 mm DC barrel opening, four M3 standoffs on the board's mounting holes and a lid slot over the full 36-pin double header. Walls are 2 mm. Print the base flat in PETG.
An Uno case is only 68.6 × 53.3 mm and the Mega's double header will not clear it. Open the ready-made model in SpeakCAD for free, adjust any millimetre in the viewer or the chat, then download the STL.

Click Get it now on this page and sign in: you can open the ready-made model for free, and the example prompt is filled in if you want the AI to redesign it. The model renders in your browser, nothing to install. Change any millimetre in the viewer or the chat (AI changes use plan credits), then export a watertight STL or 3MF with a Maker or Pro plan when you want to print.
Start from this working example and replace any number with what you measured: Design an Arduino Mega 2560 case, 103×55×25 mm cavity, 13×12 mm USB-B and 10×11 mm DC openings, four M3 standoffs, header slot in lid, 2 mm walls.
An Uno case is only 68.6 × 53.3 mm and the Mega's double header will not clear it. In SpeakCAD you open the ready-made model for free, change it to your measurements, then download a file sized for the part you actually own.
No. SpeakCAD runs entirely in the browser: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL or 3MF.
