Punch The Bag w/ Brocky Ralboa!

This is Brocky Ralboa (totally not rocky) and a speed bag. Have fun timing his punches to land solid hits on the print-in-place speed bag! Change how he hits the bag by adjusting the elbow!



Key Notes:
- When printing, I would recommend keeping track of what parts are what and physically separating them on the base plate (I.e Right bicep and right fist go together, left bicep and left fist go together. If this orientation is not correct, the model will not be animated correctly and may lead to breakage)

-If a part feels tight, wiggle it around and work it in. Parts are printed with tight tolerances to keep the model together---get some elbow grease in there! This is especially applicable to the speed bag and the connection between the bicep and arm. Brocky just needs some stretching!

-When using the crank, spin counter-clockwise for the best-looking motion (or intended, it works both ways, but I like how it looks this way more :D)


Printing Instructions

- What I used: 2 walls, 15% grid infill, tree auto support

- Support IS NEEDED, turn on auto support!

- Any filament works well. I used Silk for aesthetic reasons and normal PLA for strength (Gears, shafts) 


Assembly Instructions (Looks intimidating, but is really simple)

1. Assemble the arms by first pushing down then twisting the fist onto the bicep (Pegs can be FRAGILE, and make sure they're in the right orientation, and not flipped or mistaken for the left/right pieces, respectively. Make sure the fist's wider side is on the same side as the peg) 
   • Repeat for other arm
     
2. Assemble the body 
   1. Insert the smaller shaft onto one of the shoulder gears
   2. Insert the assembly into the body piece
   3. Attach the second shoulder gear and push both gears flush with the body (Make sure it is pointed opposite of the previous shoulder gear) 
      • Pro Tip! Work the assembly to ensure a smooth motion after full build
        
   4. Assemble the Base, Body, and Driven Gear
      1. Insert the large shaft into the double-gear
      2. Place the gear on the body in it's cutout area
      3. Place the gear+body assembly into the base by inserting the assembly TOGETHER (be careful, this will slightly bend the enclosed receiver on the base! See the bend?)
      4. 
   5. Assembling the Arms, Base, and Body
      • Place the previously built arm assemblies onto the base FIRST through the slotted portions and the small pins on the mountains on the base
      • Insert the shoulder-gear pegs in the biceps (Will require you to rotate the gears
      • 
   6. Final Step → Attaching the Speed Bag
      • Slightly bend the legs of the speed bag (after loosening the chain/bag joints) and place it on the pegs on the back of the base
        
         

Done! Have fun!
