QuickSlide: X-Acto Blade Gravity Knife &Fidget Toy

I made a 3D printed gravity knife. It is designed to hold a #11 hobby blade. There are two plates, one with the main handle bodies and the other with the 3d printed blade and connection pieces. You can move them all to one plate if you want everything a single color, or mix and match as you wish. 

The design has two primary configurations:

• Functional Tool: Uses a standard #11 metal blade for craft and utility purposes.
• Fidget Toy: An included blade model allows you to print a dummy blade. This version is intended for use as a fidget toy. My son loves it :)

Features

• Mechanism: Uses a gravity-assisted slider for one-handed deployment and retraction of the blade or fidget blade.
• Locking: Includes a printed “cap” to secure it closed so you can carry it with you. 
• Grip Options: Two different bodies to choose from:
  • A smooth, minimalist body.
  • A textured body with a hex-pattern grip.

Hardware Required

• For the Fidget Toy: None. All parts are 3D printed.
• For the Functional Tool: One standard #11 hobby blade.

Assembly Tools

• Pliers 
• Snips, Sandpaper, or Razor blade
• Optional: Super Glue

Assembly Guide

NOT MENTIONED IN GUIDE: If you find the studs/nubs that hold the blade fall out, or just want to extra secure them, simply add a bit of superglue before you squeeze them together. 

Safety Notice

If you build this tool with a real #11 blade, it is a functional cutting tool with a very sharp edge, not a toy. Please handle it responsibly and keep it out of the reach of children. The fidget version using the printed blade is intended for safe handling.
