Nâng cấp Hack Pack IR Turret Heavy Arms (WIP)

IR Turret “Heavy Arms” Mod - Crunch Labs Hack Pack 001

This is a work in progress (print at your own risk)

This is a 3D-printed gear system to use the existing ROLL servo to rotate 4 other barrels to fire 4 times the ammo. no coding changes required this is purely a physical mod. 

I have a stock ender printing at very low speeds.

3D Printing Info

• Print Time: Approximately 34 hours (including barrels), 19 hours without barrels 
• Material: PLA/PETG
• Supports: Add supports for barrel-gears
• Infill: 15%
• Layer Height: 0.2 mm
• Perimeters: 4 mm

Instructions:

1. add the 4 small-gears to the 4 closest mounts and secure them in place with the smol-shafts and caps (might need some super glue in the cap if it doesnt stay on.
2. attach the 4 barrel-gears the same way using the big-shafts and caps
3. remove the #3 Roll servo motor from the build and unscrew the orange default gear.
4. install the servo into the new plate in the same orientation and screw the driver-gear onto the servo motor.
5. attach the barrels to the barrel-gears
6. attach the barrel caps (download from crunchlab's thingiverse) to the barrels (make sure you align the prongs
7. should be good to go.

Issues:

• v1 plate's firing mechanism sometimes jams against the darts and not fire
• the barrel closest to the pitch motor will have darts jam there as well
• very top heavy, might need stronger pitch motor
• reloading darts is very very challenging

Additional Notes:
I tried looking for paper tubes at Michaels and Staples near me but couldnt find the right size. so i modeled the barrel for mine. if you can find paper tubes i would recommend it to reduce weight.

You can download the barrel cap from Crunchlab's thingiverse: https://www.thingiverse.com/thing:6592454/files 

The barrel-gear is remixed from Crunchlab's Barrel_nock_cap_v1.stl

Update: plate-v2 introduces a ramp to hopefully push the darts off for firing.
