Think Fun expansion kit.

https://youtu.be/-DTr2rts-kI I wanted to make expansion parts that were simple and fully integrated into the Thinkfun scheme but was still impressive. So I thought of something that would be awesome and then designed the parts I needed to make it. The result is this mechanical arm. the kit includes: angled gears: These can be used to change the orientation of rotational energy. Bent Plate: this is good for mounting things to the face of a box or other object. Thread loop: This is meant for threading string/cabling through to manage it or transfer force over a non-linear distance. 3 way Plate: This I designed to make sturdier hinges. 3 plate: This is just a 3 hole connector, it might exist elsewhere but I couldn't find it. Finger: This is the one part that is specialized, it is used to make the claw gripper for my arm. Print Settings Rafts: No Supports: No Resolution: .2 Infill: 20 Notes: I don't think print settings are that important, it's pretty easy to print. getting gears to start can be tricky though, make sure the bed is level and you have a thicker first layer. I was able to print everything so far without any support material, some printers might find it helpful on the parts with over hang, such as the loop and bent plate.
