This is RAGE! A Foam blaster designed for short dart (Talon) systems. The key feature of this design is the fact that it uses a smaller solenoid than most other solenoid builds. The Solenoid I designed this around is about half the size of the 35mm ones that are currently popular, but it functions exactly as needed (at only 15mm stroke). You can get the hardware directly from my etsy:
Other than that feature, this is basically a primary blaster designed with competitive Nerf in mind. Fully built, this can get 150-160 FPS on 2x Fang Revamped motors with Inferno Wheels...and it can be select fire too!
. Here is a guide for every part and how I currently print them:
Front Receiver - I print it as it sits on the blaster. I add enough support to ensure i can get good bridging underneath. It can print upside down too. The less support the better as this is a very visible piece. Print at your desired resolution with 4 perimeters and at least 40% infill. I wouldn't print this faster than 50mm/s
Rear Receiver - same as the front
Grips - I print flat, so you will need support. Print with 4 perimeters and 20% infill.
Front lower housing - print just as it sits on the blaster. You can get away with no supports 4 perimeters and 20% infill
Brace -this a critical component as most of the blaster bolts to it. Print as it sits on the blaster with supports touching buildplate. You want to make sure the supports remove clean in the motor section so the motors sit flush. 4 perimeters and at least 50% infill
Magwell- This most likely will print fine for you with no supports. 4 perimeters and 20% infill
Dart Guide- this is the triangle piece. The intention is to epoxy on the solenoid, centered just below the plunger rod. This is there to guide the next dart in line forward so that it clears the rod on its way up. You may need to trim the top edge back to get the right angle for your darts. If you don't use this part, you may have issues with darts dragging on the rod, so I highly suggest adding it.
Pusher cap- flat point down
Everything else you can print without support.
As far as assembly, its all pretty self explanatory when you see the models, but here are a few tricks:
Use as little wire as possible - but make sure you use GOOD wire. The wires run from the grip and back, across the side of the solenoid.
When soldering the motor wires, make sure you have slack in the wire between each. The motors may torque a bit under rev, so you don't want tight wires. Don't be scared to hot glue around the motors and solder joints to help them from moving.
If you are going to install the Suild select fire board, you will want to make sure your wiring is very tidy. You will then run the POTs to the dedicated holes in the front housing. On off and select fire switches go on the other side. You wont have to do any of this if you are going to run it as semi auto. I am going to add plugs to cover the POT holes eventually
The Rev switch is designed to slide over the tab of a 15/21a microswitch. You can either glue it in place, or put a slight bend in the Tab so the rev switch stays on.
Trigger- Basically floats between the 2 sides of the grip, so you can run one long screw from one side, or a short screw from both sides to give it a pivot. Obviously use a screw with a smaller OD than the trigger's ID.
Front Muzzle- Turn it so the angle of the face is touching the buildplate and then use supports.
Rails- You'll want 4 perimeters and 50% infill on the top rail. Bottom rail is OK to print with less infill, but you'll know better than me what you plan on doing with the rails!
