This is a remix of “Yet another useless box with Arduino and 5g servo” (https://www.thingiverse.com/thing:1258082)
There are three modifications:
- Micro 5g servo was replaced by 9g servo (“UselessBox_Main_9g.stl” and “UselessBox_Arm_9g.stl”)
- Arduino pro mini can be placed in the modified bottom cover (“UselessBox_Bottom_promini.stl”)
- The inscription "Useless Box" was removed from the top cover (“UselessBox_Top_modified.stl”)
All other parts and sketch for Arduino can be downloaded from the author's page (https://www.thingiverse.com/thing:1258082)
Supports are needed to print “UselessBox_Arm_9g.stl”.
Plastic arm (which comes with servo) should be shortened (otherwise, the servo will not be able to rotate).
