Thunderbolt Siren 1003

thingiverse

We are finally releasing some of the STL's for our Mini Thunderbolt 1003 we have been working on for the past few years. I haven't had al the time in the world to work on this so it's not perfect but it works. I have attached a bunch of different STL's that include the new chopper/rotator box designs. At this point we are reaching out with the 3d printing community and are looking for help. Everything was designed on Tinkercad. If you need me to share my Tinker stuff so you can edit it, just let me know. I added 3-4 different choppers. The original 4/5 port which I designed to look just like the original Thunderbolt Chopper. I also added a custom 5/6 port chopper with a flat top to add better air flow and an open style. The 5/6 port sounds deeper in my opinion. All of the choppers have the holes to fit the 4mmx30mm rod and 2.8 mm chopper motor. I had to tap the rod into the top of the chopper due to it being a tight fit. I added my chopped design tool STL. It’s what I used to design the 4-5 port chopper. I don’t have one for the 5-6. There are two different size rotator boxes, the small old version and the big new one. The top assembly Motor casing/bottom stator and top stator, all slide into each other. The motor we are using is a A2212-6T 2200KV Brushless Motor + 30A ESC for plane/helicopter that was purchased on Ebay, but it's also availabe Amazon. There is also a basic $7 12v R/C motor that Amazon and Ebay sells. I've included the stator for that as well if you want to go that route. I found that the A22 kit is perfect. It allows the motor to breathe and comes with a few extra things to keep the chopper in place. With the regular RC motor I was having issues with it heating up and melting the PLA, even though I made several housings with ventilation. The A22 uses 4 screws that will screw right on to the motor stator and allows flexibility. I'm using an inflatable bed air blower for now. For the rotator I used a 4 speed gearbox that I bought off of EBay. I used the small gear and customized it to fit on the rod that comes with the kit. I had to cut the rod to fit in the rotator box. I used some 2GT belt for the pulley. The top gear fits over the pipe that’s sticking out of the rotator box. It’s slides right over and the lid for the rotator box fits in the pipe with the gear attached to it (I’ll thy to get better pictures). I'm using a 13x5x4 4mm inner bore. The bearing has a rim. I picked up several other style bearings but I haven’t tried them yet. I added the link for the bearings that I’m using in this. I’m sure you can get the same size on EBay or Amazon. I purchased some 4x30mm rod shafts that sink into the top of the chopper stator and into the chopper. https://www.th3dstudio.com/product/creality-y-axis-belt-idler-bearings/ Using a 12V 12amp battery and a 6V 6amp for the rotator. A small collector ring assembly that can be bought on Amazon/Ebay. I added a photo of the style of collector ring that I used. I would keep it around that size. I used a 12 wire collector ring you have to have 4 wires for the solenoids, 2 for the motor power and an additional 3 wires to connect to the ESC controller. You will also need an ESC tester to control the motor speed (around $5 for a two pack). It’s always good to have a couple extra wires in that collector ring just in case one goes bad. We are still waiting for some other switches and other stuff in the mail. I used a pulse / relay controller for the solinoids. I used some basic 6-12v small solenoids that didn't work great and I'm still hunting for something different. I will update this page with more info! I have uploaded a few closeup pics. the once from my Youtube video is the older style. This new one has not been uploaded to Youtube yet. This has been a ton of work and was built from the ground up. Any help would be appreciated! Please comment and let me know what you think. Attached is my YouTube channel with some of the videos that I've done. It's been a minute since I have had the chance to post my updated videos. The siren in this video is version 1 and not the new style. I added some of the STL’s from the original only from the rotator box down to the blower box. These videos are a couple years old but will give you an idea how it all comes together. https://www.youtube.com/watch?v=iySnTFvJoLA&themeRefresh=1 My Youtube channel name NTXSirenFanatic I have used Cura for all the slicing. PLA from Overture -200c, Inland (MicroCenter filament) 210C (it’s your choice). All was printed at 0.2 resolution - This was a lot of test prints so it saved time and looks decent. I have an upgraded hot end (E3D V6) so temperature may be slightly different on yours. Please don’t bring PLA over 215c if it takes more than that, there is something wrong with your thermistor reading. Bed Temp - 60C Speed - 50mms for most 150+ for others No change in retraction. Supports : Yes -Tree supports in Cura make removing supports a hell of a lot easier. Infill: 20-50 PLA: inland and overture Matt Yellow and Gold I have an Ender 3 Pro with the Ender Extender kit 400 x 400 x 500mm build volume so I was able to print this pretty big. I didn't include the small control box since I'm unable to find it lol. Let me know your thoughts.
