Cardboard Construction Tools Set

This set it is the best collection of pieces I could find for makedo style cardboard construction tools for kids. I tested about 5 different saws, punches, keys and screws and these are my favorites.

This brings together a chain of remixes (including my own modification removing one end of the punch - not pictured in the photo) for the cardboard cutter, punch, key and screws. And brings in another chain of remixes for the folding tool.

The folding tool has an optional punch you can print and have it stick out the bottom.

I printed everything in PETG 3 perimeters at 15% infill. Nothing is particularly fragile but I haven't had my kids use it for too long.

I'm still evaluating hinges and other parts and might add them too, welcome to suggestions!

Update 12/4/24: Added a Hole Punch that works quite well.

Update 12:31/24: As people have noted in the comments the saw breaks pretty easily, but johndoe_2629479 remixed the saw and gave us “Stronger Saw”!

This is a remix of a remix of a remix: 

• Original by wyliebutler at https://www.printables.com/model/257606-cardboard-construction-screws-for-the-classroom
• Remix by WHerzog at https://www.printables.com/model/330729-handtool-for-cardboard-screws 
• Remix by Qbi at https://www.printables.com/model/739295-cardboard-toolset

I've taken the punch tool and removed one pointy end as it failed the “Can the parents use this without hurting themselves?” test. I've copied without modification the saw, key, and screw.
