3 Hole Punch

This is a simple, fully 3D-printable 3-hole paper punch made for standard binders. It uses a hinged design with three aligned holes and a removable pin so it’s easy to assemble and works smoothly once put together.I designed this as a lightweight, practical alternative to a store bought hole punch. It prints easily, doesn’t need anything fancy to assemble, and gets the job done for everyday, light duty use. What it does:- Standard 3-hole spacing- Simple hinge with a removable pin- Easy to print, minimal fuss- Compact and portable A few notes:- Printed with PLA- Not meant for heavy stacks of paper- Strength and performance depend on your print settings- Needs supports- Around 5 hours to print all parts Assemble:1) Put Part 2 on top of Part 1, so that the parts are lined up correctly. 2) Slide Part 3 through the new found tunnel, while then enclosing it with Part 3.5, locking the axle in place. 3) Slide Part 4 through the opening in Part 2, finishing the 3 hole punch.4) Enjoy!
