Ray gun, LED enabled

This is a sliced-up version of https://www.thingiverse.com/thing:2091732
It's enabled to insert a 3mm LED in the front and use the trigger with a push-button and a 9v battery in the grip.

Recommended to print in colored (red) PLA and then paint the other parts in silver.
I printed it in transparent PLA and painted it except for the round end of the nozzle. Makes the nozzle look nicer but it's not that easy to get a nice and even paint job.

Requirements:
--------------------
* A 5v 3mm LED with integrated resistor like this [here](https://www.aliexpress.com/item/33011399799.html?spm=a2g0o.productlist.0.0.64a34bc3tH5hvU&algo_pvid=e344910d-2f5b-4810-8f3f-e2966c27110c&algo_expid=e344910d-2f5b-4810-8f3f-e2966c27110c-0&btsid=0b0a556216163315010865004e2eb3&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_)
* A micro-push-button like the flattest one [here](https://www.aliexpress.com/item/32982683234.html?spm=a2g0o.productlist.0.0.1125693dUszTHu&algo_pvid=069c160d-b1b4-4395-
