A 3D printed kit for BJ the Robot from 13 Sentinels. He's just a cute lil guy but this is a big project! BJ stands at roughly 24” tall when finished, which is 1:1 scale. He is over 50 parts total.

He has some articulation, including the ability to turn his head. This is especially handy for making him look at the camera; it makes him more lifelike! His head is hollow and is designed to install lights/electronics, and he can be largely assembled after painting.

While his wheels can roll, because the original design has his legs in a V shape, he doesn’t roll very well. You can just permanently seal wheels to their chasses if you'd like.

Assembly Notes (Required hardware for each section is listed below):

• The front and back plates for the head are printed separately to make painting easier. They can be mounted permanently or they can be removable with the included magnet slots. I suggest just permanently mounting the front after you’ve painted it and leave the back removable if you want to be able to access electronics for the eyes or take off the head. Because the fit is fairly tight, you may want to add a loop of ribbon or something on the underside of the back plate that sticks out so you have something to grab to pull it off.
  
• The eyes are hollow and can be printed in clear filament (or clear resin) so they can be illuminated. The eyes slot into the front housing and can be glued in place permanently or you can use the provided 1/8” magnet slots to make them removable.
  
  
• The top of the neck has a post that slots into the head and then has a cap that goes on top to lock it in place. It’s made this way so you can mount the head securely while still being able to turn his head for photos. You can either glue this cap in place permanently or you can use the included magnet slot. With the magnet slot, you can remove the head for travel/storage.
• The base of the neck slots into the body on a post, but it also has a magnet slot. You can use this to make the neck removable from the body or you can glue it together permanently. Even if you assemble the rest of the body/legs/arms permanently, I do suggest making this one removable because you can then carry the head/neck around the con in a bag casually when you don’t feel like lugging around the whole body.
• Arms: His arms are symmetrical and reversible; you can install two closed arms, two extended arms, or one of each. You can swap them in and out as desired for photos. The base of the arm mount has a slot for a 1/2” magnet so they’ll stay nicely, but you can just skip the magnets and glue the arms in permanently too. 
• The legs are also removable from the body if you install them using the 3/4” magnet slots, but you can also glue them in permanently too.

Hardware Required - Hardware not included

• Head: Each plate takes eight 1/8” magnets, max 2.5mm deep, for 16 magnets total.
• Each eye takes four 1/8” magnets, max 2.5mm deep, for 8 magnets total.
• Neck Top: Has a magnet slot that is 1/2” and can accommodate a maximum of 3mm depth.
• Neck Base: for a 3/8” magnet, 3mm deep.
• Arms: Each arm mount takes two 1/2” magnets with a max depth of 3mm  (total of 4)
• Legs: The legs take the following dowels/spokes for the wheels. Wood dowels or aluminum are ideal as they’re more durable.
  • Front wheel: 37mm long 1/2” dowel x2
  • Middle wheel: 63mm long 3/8” dowel x2
  • Back wheel: 50mm long 3/8” dowel x2
  • Femur: 70mm long 5/8” dowel x2
