Mega 2560 3D model

This is a 3D model of an Arduino clone of the Mega 2560 microcontroller board. I needed one for an enclosure design, but couldn't find one that had precise dimensions for the mounting holes. Despite no officially-diagnosed OCD, my brain felt it necessary to lay out the full details of each component on the board.

The board design was taken from a Rexqualis R3 version of the Mega 2560 board. Components were measured for size and placement by hand, using calibrated calipers. However, due to their hand-measured nature, they may be slightly out of position by a tiny bit. I also have an Elegoo R3 version of the Mega 2560, and the layouts appear nearly-identical to each other. I imagine there are other-branded boards which also have very similar layouts. Note: These boards do differ a bit from the official Arduino models.

I've provided various versions of 3D models to put to all of your various uses. STL, 3MF, STEP, and a fully-detailed and parametric version of the Fusion 360
