Summary

Simple frame to hold the parts together. Fits Maixduino and Maix Bit boards. The TFT display is held in place by a click-in frame. There are two frame versions with slightly different cutouts. You may have to widen the FPC cable cutout by 3 mm using a sawblade at "24" side. This is corrected on the Tinkercad site already. M2 screws are used, head thickness should be 1 mm or less (file off).

Maixduino: camera holder must be glued into the frame as seen on photos. I have not used the 4th screw at the camera connector but the hole is there.

Maix bit: has a simple 5x7 cm PCB with two socket rows holding the computer board.
