----------Printing-----------

Body. . . 1x
Lid. . . . . 1x
   These are the largest parts and make up the main structure of the project.

Front Wedge. . . 1x
Back Wedge. . . .1x
   You will need only two wedges in total (one front, one back). The spikes look awesome, but the wedges without spikes work better to immobilize other bots. These are a bit of a weak point, so I would print them in ABS. It has a higher impact resistance than PETG or PLA.

Washer. . . . . . . .6x
Drive Wheel. . . 2x
Idler Wheel. . . . 2x
   Each wheel will need two washers, one on either side.

Spring. . . . . .4x
Armor A. . . . 2x
Armor B. . . . 2x
   The armor plates will be mounted on the springs to give them extra resilience. I recommend printing the armor in ABS and the springs in PETG. 

 

----------Assembly----------

Needed Parts:
     - 2 Silicone Bracelets 
     - 2 Yellow Hobby Motors (see below)
     - 4 House nails
     - 2 Small wood screws
     - Robot electronic system (battery, ESCs, Rx, etc.)

 

Step 1: Armor
     - Glue front and back wedges in place
     - Slide armor panels onto springs
     - Slide springs onto the baseplate channels
 

Step 2: Tracks
     - Using a nail as an axel, assemble the idler wheel with a spacer on either side. Include the silicone track around the wheel.
     - Attach the drive wheel to the motor (no washer) then use the wheel to stretch the silicone into place.
     - Slide a washer in between the drive wheel and body then secure it with another nail.
 

Step 3: Finishing Touches
     - Install whatever control system you have. There is not a lot of space, so some trial and error may be necessary.
     - If needed, use a soldering iron, drill, or files to install your led and switch into the top plate. Hot glue or command strips both do a great job of holding it in place.
     - Use 2 small wood screws to install the top plate.
