Im Learning about Breadboards and Arduino and was getting sick of Arduinos,Breadboards,LCD's and Keypads laying around on my desk so I Figured why not have a look for a Printable model to tidy it up. Although there are some excellent arduino,Breadboard models here I wanted one that would fit on The Flashforge Dreamers Bed and Be able to interchange between 1602 LCD and 2004 LCD. The Little Tabs on the backs of the LCD's are a pain so I ended up screwing 6mm Plastic Standoffs into the threaded holes for the LCD's. The Keypad Mount needs to be Higher and somewhere to tuck the Keypad wires out of the way would be an improvement. Might even look at a few drawers underneath for jumper wires and components.

Edit: I have added a few more things to this. A small Chest of 4 dawers. Arduino Nano,Uno and Mega Holders Half and Full Breadboard Tray. have split the Main Platform and Full Breadboard into 2 halves for easier printing on small printers. have added slot under Keypad to allow flat cable to go down through and come back up in front,I just super glued the connector to the plastic. also added a dovetail along front and on component holders to allow slide on connection. Hope its helpful
