hi submitted first draft of the 3d model of box opener tool the size is as per you mentioned.

This is good, but as it said in the description, the blade needs to fit the one I showed with measurements. It has 2 notches at the top, of very specific measurements. This design only has 1 notch at the top. Please follow my measurements closely.

The blade that has to fit into this new product you are creating is the blade with the dimensions I have in the description. It has 2 notches at the top, with very specific measurements. These measurements have to be correct for the product to function properly. Please pay close attention to the measurements. Your final product will include a PDF from multiple angles, with measurements.

Hi Project Owner,
i have submitted a design.
I've attached a 3D pdf file
To view this file you need to use Adobe Acrobat.
Let me know if you are having trouble to view this file.
I have prepared a video on how to open it .

Please make sure your final submission is a workable box-cutting tool. The blade should be held in place by something.

The blade will securely position onto the embedded pocket.
Installing it, Tilt a bit the knife cutting and firmly press to the pocket.

Changing a blunt knife,
there 2 eye-like holes, 2 ways to take the knife out
1) flip the knife using the eye-like holes ( nail ,tweezer or minus screw driver)
2) Push the knife opening eye-like hole from base bottom ( small rod)

Hi. I sent an entry for your project. It wasn't finished yet. Just want to show you how it looks like for now.

I sent the 3D preliminary work. I request you to return.
