Breadboard Kit

This is something I have been working on...it's a breadboard kit with some extra goodies onboard.  The green things will be some pots with mini breadboards, and next to them are some LCD volt meters (they are not going to be super accurate, but good enuf to hopefully check if something is 3.3v or 5v).  The blue colored block will include two DC-DC buck converters and a component tester.  The whole mess should fit in a Stanley storage box similar to the others I used (which is the reason for the strange shape).  If it all works out, I will be able to fit two of these in one storage box, and I may make different modules or arrangements if I decide I need something specialized (I have been thinking of including a portable DSO on one of them).  This project seems like it is about 70% done, but will see.  There are a lot of parts that need to fit and that is always difficult.

This is not fully my work however, parts were re-mixed from others "things" on Thingiverse.  When completed it will be posted with all the attributions, but below are the ones I used to help with this project:
