FDL-1 Prototype

thingiverse

Update This thing is more or less deprecated. There is a new version here: thing:1651854 Please visit FDL1.com for more info. I have a webshop there selling assembled blasters, kits and electronics bundles to pair with your printed shell. The FDL-1 is a robotic foam dart launcher. It is high powered, fully automatic, web enabled, and can be converted between blaster and turret forms. It shoots Nerf Mega size or compatible darts. This is the prototype version as seen in the FDL-1 Kickstarter. I plan on redesigning a good portion of the FDL-1 in the coming months to box in electronics and round a few edges but there was a lot of interest in the prototype design. Here it is:) The major electronics will stay the same between versions. I will post the improved design separately when it's ready. I'm working on a more complete list of electronics and hardware, assembly instructions, source code, videos, etc. Everything you'll need to get up and firing. A full FDL-1 print including a handle and turret can take up to a week on a single printer depending on your print settings. I wanted everyone to at least be able to get that process started. I'm also working on getting a web shop setup to sell the FDL-1 as 3D printed kits, fully assembled, or just the electronics and hardware so all you have to do is print and assemble. Other designs and accessories to come...

Print Settings Printer Brand: Printrbot Printer: Simple Black Rafts: No Supports: No Resolution: .2mm Infill: 20% Notes: There are a few parts that need support but I have built it into the models. You shouldn't need to turn it on at all. A mm or two brim might not hurt on parts without a lot of surface area on the printer bed. The entire model was designed with a 0.4mm nozzle in mind. I'm not sure what effect a different size would make. Darts may fit a little tighter or looser in the revolver. The same goes for screws fitting through holes and into threads. My current printer has a 6" cube max print size. Some of the parts push each of these dimensions so that is the minimum you'll need without slicing parts into smaller pieces. I haven't tried printing the FDL-1 in ABS yet. I will soon. PLA works well because it is more rigid. I always use a heated bed, even for PLA. BuildTak is pretty nice too. Please note, I've gotten feedback that the revolver will not print on a Lulzbot Taz 5. I haven't had issues printing it on my Prinrbot Simple Metal though so I'm not sure if it is a model issue or something more specific to certain printers. If you are attempting to print your own FDL-1, print the revolver first because of this and also because it will take no less than 11 hours to print. If you have issues please send me a message so I can work them out before the next version.
