3D Printed Micro Match Connector Crimp Tool

I have a project that involves Micro Match connectors. They are similar to IDC connectors, but with a lower profile and a zig-zag pattern.

I had to crimp one connector onto a ribbon cable, my first attempt using a vice failed miserably, instead of the conductors being forced into the teeth properly, the forces instead crushed the connector. Unlike a IDC connector, which is mostly solid plastic, the Micro Match connectors are pretty hollow, thus weaker.

3D Printed Peristaltic Pump

I 3D printed a very durable peristaltic pump. It is capable of pumping very thick liquids at as much pressure as the tube can handle. It is durable because it is printed at 100% infill at high thicknesses and uses steel ball bearings. It is capable of such strength because it is using a massive 12V DC brushed motor that has a 150:1 gear ratio metal gear box, which means several kilograms of torque.
