Crazy update 4/9/2018: I would still built it the V4 current but i get requests for a finned version. I added the parts Yando R triforce fin and Yando R triforce tail fin, you print both parts and use them instead if the other rear arm and motor mount. this parts if they work will make it driven by rudder fin and the set up should still in theory be the same. let me know if they work for you if not tell me what i can change to make it work.

Please note most parts are in the V3 folder I left the V2 parts in the main zip for Older users that need V2 parts thou I believe all parts are exchangeable between them.
V1 parts are outdated and anyone using them please use V2 or V3 parts.Area 51 bottom plate is in main folder.

Updates:
Dec 29th 2016 Update Added optional Area51 Bottom Plate that takes place of weak nose area that is the weakest part ,it also rids it of the need for 2 cushion balls, but you can pick which version works best for you. also if you already have the TRiForce you can just go get the part alone here http://www.thingiverse.com/thing:2003212 Thanks Ill keep making it better!

Oct 2 2016 Update: After printing a few more I want to update again to help out the folks wanting to build this craft. Its now better than ever and easier to print.
First look at the V3 zip it has all the latest changes mostly in the nose/camera section.
I started using a product Airwolf Wolfbite its a game changer and I can now print all the parts in 2 sessions instead of one part at a time with tape. Plus the warping is extremely minimal if any. Get some!

What is this?
This makeover remix covers problems and simplifies printing for the SB and TD. They are both wonderful and well engineered. This allows lower priced very common gear and easier assembly. You could not ask for a better platform to build upon, so here is what I changed.

Top plate has a slot for a naked Orangerx r615x and a place for 2 antenna.
I also beefed up the FPV gear section of the top plate. It will house a Mini system I broke 2 just trying to get gear into place.

Middle plate has been extended and a fence added this helps protect your gear in a crash. The unneeded large bearing holes closed so no more need for bearing plugs.
The rear extension has coverage for the new rear arm that normal ESC will fit.

Rear arm fits 9 Gram Turnigy and similar servos and better room for SimonK ESC and wiring.

Bottom plate had unneeded large bearing holes closed so no more need for bearing plugs this is where the landing gear now mounts.

Added Landing Gear, this simple gear set protects the battery, and gives more stable take off. This gears have plug feet also , which can be printed in rubbery filament.

Added TVL Non backplate camera support (tvl600) so you can fly without a camera or with normal modern sealed cameras without backplate .

Updated July 8th Camera Tray has 2 Versions Triforce Lower Camera Tray old which prints with Supports or facing up, Or my V2 which splits this in 2 for way easier printing without support since this piece gave me printing nightmares and was the last piece fixed. Updated July 8th please see Oct 2 16 ,V3 which is even improved over this update.

Update August 7th
Over 250 Downloads WOW! I didnt expect this much response Thanks!
Tried the Lemon Rx feather weight. It fits with only a little razor knife needed but its lack of CPPM makes its wiring very difficult. I would stick to the OrangeRX r615x with CPPM for now.. I also tried the TVL700 Eachine $25 mini FPV set from Banggood and it fit great without any hassle and the video is clear ,because of the channel button it has to be justified left which actually works out better for the antenna. The Front ESC's have enough room to fit inboard right in front of the Flight controller which I now am using a power distribution board on worth the extra $5 for sure as it cleans up all the wires. Ill add pictures as I get complete mabey even a video.

Only files unchanged are Trident arms R&L .But i may soon change them also for my further liking,,,, but they are included so you dont have to hunt them down to build.

I also included a Antenna Array and Deans plug holder if you wish to add them.

What you need is a 3X motors &ESC for a 250 size craft, 9 gram Servo Turnigy, a 1200mah battery, Cleanflight Tarot FC /SP Racing F3 or similar with small pins and 90 degree outputs, a bunch of different screws,and a Orange 615 old or new types will both work.

Also With Multirotors in general use screws that go more than half way thru arm and then finish them down from the other side with a shorter screw and reverse the direction for the next screw in the same arm. This makes the arms VERY VERY crash resistant. because most breaks happen at the thick parts of the arm but screwing them this way is very close to bolting them all the way thru but prettier to look at.
