This is an angle grinder a friend asked for his kid. It is made up to require minimum supports and be printed in different colors.
In the render you can see the color choices I made. There are bolts to join the AG-Base with AG-Middle, and the AG-Middle with AG-Head. In case you are having trouble with that you can skip it and just glue it together. I though that it was going to be stronger this way.
There's a cube to join AG-Head with AG-Motor becase there was no room for something else. Again, you can just glue it together.
Finally, you can glue or just stick the AG-HandleBolt to AG-Handle, and that is meant to be removable.
The design is mean to have a disk that rotates (using the hand to make it spin)
Supports:
The only parts that require supports are AG-Head and AG-Motor
