Breadboard with integrated PSU

Why spend $$$s on a breadboard mount when you can 3D print one for pence? I designed this 3D printable breadboard with integral battery power for my 7 year old son to learn electronics with.

This 3-part object fits two standard-size breadboards, two banana sockets, a potentiometer, a rocker switch and DC-DC converter with displays. I swapped out the pot in the DC-DC converter so we can control the voltage from the board and I set the current limit using the internal pot to 0.25A because I don't want my son overloading the LiPo cells I used to power it.

Perfect for Arduino projects! :-)
