Arduino powered Portal Gun - Modification and shopping list

Moved to printables. Please use following link: https://www.printables.com/de/model/795771-arduino-powered-portal-gun-modification-and-shoppi To make your own Portal Gun with light and sound you need parts from here: https://www.thingiverse.com/thing:3579224 and change them with parts from here (Filenames will guide you). https://www.thingiverse.com/thing:4641037 And now you are done. Follow the instructions in the second link form Lunchbox7985). But if you like my remix from the button-hatch with three arcade-buttons instead of two AND if you got a large printer like the FLSUN QQ-S Pro and want to print the white shell-parts in one piece you have to change the white shell-parts and the hatch-Part with my parts as follows. I printed the white shell-parts of the case each "in one piece" on a Flsun QQ-S Pro. This worked great and so I didn't have to worry about gluing it all together. The designer of the Arduino Portal Gun used a 2.5 inch tube because he lives in the USA. I had overlooked that when I printed the "modified_collector.stl" part. So I needed an adapter to be able to use a 60mm acrylic tube. So get the right tube and print the right part before you print ;-) Otherwise you can use my adapter "PG Acryl Rod Adapter.stl". Or you print the right part from Lunchbox7985: "modified_collector_larger_center_hole_original_outer_size.stl". The last modification is for the Generator Hatch for the buttons: I modified the case cover to fit a total of 3 arcade switches. The white button is for "Cancel Portal" and only lights up when there is a portal to cancel. (You need a slight modification of the software for the Arduino, I attached the source code file, and you have to connect the LED from the white arcade button to port "A3" of the Arduino (right next to the connectors for the two portal buttons) The Cancel button can be operated comfortably with the little finger. The power-up switch (in the middle) can be operated with the knuckle of
