A thick base to mount Arduino Yun board. Right side is long enough to protect SD card installed and has a 20mm hole to fit a Grove sensor module if needed.
29/8 - Added a stand to keep yun+base on vertical position.
Update: It also holds Arduino Uno boards (it has same shape as Yun)
Printed using 1.75 PLA at 0.15mm layer height and 60% filling.
Screw holes fits 3mm screws up to 10mm long (the hole near the pin sockets requires a very small head screw, but the other three are usable)
