3D Printed Exclusive Joints
After building so many wheelchair costumes and using 3/4" PVC pipes for most of our frames, we've discovered that there are times when you need a joint that doesn't exist. That's when we break out CAD and design our own exclusive joints to help build these frames. Check out the joints we've designed and what we used them for. (NOTE: We recommend printing them at 100% fill so they are strong enough.)

Parallel Through:
This joint can connect to any straight vertical bar on the wheelchair. Zip tie it to the bar with the 3 premade trenches. Then a 3/4" PVC pipe can slide all the way through on the other side. This allows for additional support in locking down the frame of the costume to the frame of the wheelchair. |

Long Tee Joint:
This joint can serve as a pivot point by attaching onto a PVC pipe side. The two trenches are for zip ties to secure it down and not slide off the joint. Then slide a PVC pipe into the top and use the tiny holes to screw into the pipe and lock it in place. (NOTE: These work best printed in flexible TPU filament.) |

Caster Wheel Attachment Joint (Generic):
While this is most commonly used for caster wheel attachments, it could be used for other things too. This is if you need to attach the end of a PVC pipe to a flat surface such as a piece of wood. It has four screw holes for base and two screw holes to secure the PVC pipe into it. |

Caster Wheel Attachment Joint (Swivel Caster #69847):
These custom designed joints were specifically designed to fit a particular caster wheel. That way, it screwed directly onto the actual caster wheel and didn't require any wood between the two. There are 2 versions of this joint. V1 is sturdier, with straight sides and is stronger. V2 is rounded, still sturdy, but takes less 3D printer filament. Both work great and we don't recommend one over the other. (NOTE: The bolts used to attach these together are 1/4 20 pan head bolts.) |

Wheel Caps for Small Stroller Type Wheelchair:
These wheel caps allow for a wheelcover to go over the back wheels of a stroller type wheelchair with mag wheels or a manual wheelchair with spoke wheels. The graphics for those wheels can then stay upright at all times by using ballbearings and weights at the bottom of the design.
