Ray gun, LED enabled

thingiverse

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-bd91-8935e0392761&algo_expid=069c160d-b1b4-4395-bd91-8935e0392761-38&btsid=0b0a556016163307219718844ef5b6&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_) * A 9v battery connector like this [here](https://www.aliexpress.com/item/4001007666600.html?spm=a2g0o.productlist.0.0.556f62bdURioqF&algo_pvid=0468015f-0b35-4bd8-b6f4-78fee256abd0&algo_expid=0468015f-0b35-4bd8-b6f4-78fee256abd0-0&btsid=0b0a557216163315592856659e6773&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_) You can also use 3v LEDs and then use AAA batteries instead. Print instructions ---------------------- I added mouse-ears to the 2 halves, so no prim required, use supports on those. The trigger does not need supports, but brim is recommended. Connector and nozzle just print as-is. Battery grip needs support. Post-Print: ------------------ Sand the area of the 2 halves where the connector and the battery cover touches them. Make sure that the two halves connect without gaps when those parts are inserted. Cut off the mouse-ears. Assembly -------------- * Solder the wires, LED to the push-button with one wire, the other one to the Battery connector, The second battery connector to the corresponding push-button connection * Glue the push-button, to the front-ledge of the box the trigger will fit in so that the trigger actuates it when pulled. * Glue both halves together. * Glue in the connector. * Then glue on the nozzle and make sure it's rotated in the proper direction. Don't glue the battery cover, obviously. Post-production ---------------------- Sand the whole thing so that it's smooth. Tape the little ball at the end of the nozzle so that it stays transparent Paint the gun as desired
