3D Printed Case

A project log for USB Tester

The USB Tester makes it easy to monitor the current and voltage of any USB device (and non USB).

The last few weeks/days have been trying to tweak a 3D printed case to fit the USB Tester snugly. Between dealing with the printer and tweaking the design, I have had a hard time getting a good fit. The design is a two piece that separates the same way the USB Tester does from the backpack.

I need to figure out a solution for the LED. If I use semi/translucent filament it works nicely. For solid color filament I need either a hole or a setup for a light pipe but the LED is so close to the supports for the button. So it'll probably have to be a small hole or just stick to translucent filament.

I added tabs to hold the PCB tightly, but at this point I need to move them closer to the PCB and maybe add another tab below where the button is.

The last thing is to have holes so you can use the base with banana test leads. They would slide through the Tester and through the bottom of the case. Or I could just make the case have more space between the base and the case to allow for more room for the banana leads.

Here are some pictures of the progression. This set was printed with a Micro3D. I will do another post with pictures of ones printed with a Wanhao Duplicator i3.

The little pieces on the end are the buttons that fit into a the hole with slots for the arms of the button. This design works quite well. I have to give credit to my co-worker for giving me a another set of eyes to look over the design.
