Arm box base for bluetooth temperature logger.
With this 6th version package includes a non-logo version so you can use it for your own electronics project.
Also fixed a bug about the bottom part's bandage holes.
After printing use M3 bolts. For cover bolt holes are 3mm but for the other middle and base parts it is 2.8mm. You can drill these holes if you have any hardness with a 3mm drill bit.
