This Adventure Time family cosplay group is too adorable. I love when everyone gets in on the costuming fun! Instructables user and mom ecsaul23 said they build a “ride” for the kids to go with their Halloween costumes every year, and ths time Lady Rainicorn fit the the bill. She’s more than just wheels though; she houses a conveyor belt that delivers “unicorn poop” cookies (hey, I didn’t name them). She initially tried to run the conveyor belt with an Arduino, but it didn’t quite work. They ended up pairing the belt with a remote control car. Very creative! Here’s some information on how they put together the belt:
Get two long cardboard boxes. This part worked well having two of the these boxes so that you dont have to worry about sizes not lining up.
Cut or tear apart the side where the box is connected to make one long piece of cardboard.
Put the webbing on the two spools and hold it together to make a belt. With hep, pull apart the spools to the length you want the conveyor belt to be and draw a rectangle around each spool on the cardboard. Sit the belt and spools aside and cut out the rectangles. ( photos 3-6)
NOTE: the belt wont work if its stretched tight. it needs some slack. We had to resize our holes to give more slack.
Now thread the webbing through the holes. Put a line of hot glue on the edge of the end of one end and press it into the other end to make a belt. Hold until glue is dry. Now use needle and thread to sew the ends together for extra hold. (photos 7+8)
This now keeps your belt on the base and you can insert the spools with ease.
We need something to go through the spools to allow them to spin and to hold them in place on the base. We cut a small strip of cardboard, score it down the middle lengthwise an fold it over. then slide it through the spool. It should be sized to allow the spool to rotate freely and stretch from one side of the hole to the other. Do this for both spools. Sit these pieces aside for now.
