A toy Bear Trap I designed for a friends son to catch all those pesky bad guys skulking around the house!
There are 2 versions,
V1 - smaller parts, requires cardboard for teeth/jaws and base support. See the above video for instructions on how to build that.
- Both V1 parts
V2 - Bigger! Full Jaws and base, can use double thick cardboard or print the tooth in TPU for maximum FUN!
- Both V2 parts
- Tooth x21 (Optional, TPU @ 20% infill. Less infill for softer teeth)
- Plastic! Printers preference! I used PLA for all but the teeth.
- Rubber bands
- Superglue, for the pins.
- Cardboard for V1 or V2 teeth.
- TPU for optional teeth.
All but the pins can be 20% infill.
Pins must be 100%
I only used support for the pins just to keep them from breaking loose but you may need a brim because of the caps. They will probably need some knife cleanup.
V2 will need more rubber bands then V1 because more mass.
This thing has a hair trigger! If it's not staying set then just add more rubber bands.
Set and Enjoy!
All holes and trigger mount pins will need a little knife/drill work to make them round enough, depending on your printer.
Shave pivot points as needed for smooth operation.
Pins should be installed from inside to out with the cap glued onto the outside.
The pins nearest the trigger need the flat side down or the rubber bands won't fit over them.
The trigger will need some force to get it onto its pins so be careful.
TPU teeth are held in by friction. Place as required.
For more detailed build instructions see the video at the top, the design is functionally identical.
