Fully 3D Printed Spider Jump Scare Box! I've pre-oriented all of the parts to print in their optimal printing order. This print requires no glue and no strings, everything that needs to be attached friction fits together. 

Settings: 

     -There are no specific settings required for this print, just be sure to preview your print before sending it to the printer. 

     -I printed everything at .2mm Layer height with .4mm Line Width and 10% infill. 

Post Processing:

     -The spiders front legs need to be bent down slightly after printing so that it does not catch the lip of the box when deploying. 

     -If you can't achieve a friction fit, some super glue will do the trick when attaching the spider to the rotating arm. You can also scale the spider up by 1% so the friction fit isn't as tight but still snug, if you do this and someone opens the box quickly the spider will eject at them which is kind of cool!

     -Place a piece of filament 

Assembly: 

     -Slide the center pin in between the rotating arm(this is an EXTREMLY tight friction fit, I used a 3d printed hammer to wedge the pin in between.

     -Press the spider onto the tip of the rotating arm. 

     -Slide the assembly down the center slot until it pops over the built in retaining pins. 

     -Once placed into position rotate the spider to an upright position (it's final position where it will be once the lid is opened)

     -Slide the lid into the box. Once pushed far enough forward, the track on the lid will meet the gear and rotate the spider out of the way for the lid to completely close. 

     -Once the lid is completely closed, slide a piece of filament down the two holes in the top of the lid. This is to prevent you from pulling the lid completely off when opening the box. If you don't put the filament you will have to stop opening the box before the gear runs out of track to move on. 

     - Open the box once the filament is installed to ensure that the spider assembly swings freely out of the box (the faster you open the lid the faster the spider moves). 

     -Place on table/flat surface where there is heavy foot traffic and wait for your first victim. 

BONUS!

     -I've also included the STL for the spider. It is extremely easy to print and was designed with 3d printing in mind. Most other spider models out there are difficult to print, not this one =]
