My egg cracking skills are as a bad as my joke telling skills, the number of times I have tried to crack a humble egg into a frying pan and failed are too numerous to list, thus that's why I decided to design and make my own Egg Cracker, there are these type of scissor action Egg Crackers out there, not sure if there is a 3D version but the majority have blades to enter the egg, these in my opinion are dangerous and I would imagine care needs to be taken when cleaning etc.

My design has no blades, thus making it very easy to clean, just a wipe on the tip's and job done with your fingers still intact.

There are caveats to this design like everything, you have to hold the end piece's together while the points pierce the egg, once that's done its the normal scissor action to open the egg, the points are quite sharp but not blade sharp so a little pressure from the plunger is needed to enter the egg.

Cool Project to design, I had to redesign the plunger twice and the center piece was re-modeled, the components are secured with 3mm Hex head Bolts 4no @ 23mm long and one approx 12mm long I've used 3mm Lock nuts as well just tighten so there is still movement, I've used an elastic band across the top of the jaws to return them to the closed position, I doubled this up.

To use the cracker in detail you push the egg inbetween the jaws, opening the handles outwards lowers the plunger just slightly to allow this, then the egg should be snug up to the points which will enter the egg, hold the top sides of the jaws together as in the video and apply pressure with the handles, as soon as the points enter the shell, open the egg with the scissor action, to release the shell, tip upside down into a container.

This Egg cracker should be printed out of PET-G.

To print I turned the support on and printed as the preview, the supports came off pretty easily and very little clean up.

It's hard just with photos to show the cracker in action so I've uploaded a video on my Youtube channel, Type Egg Cracker in the Youtube search box you should find it. there a few videos on my channel with some Robots etc, please feel free to take a look.

I started to use Youtube to embed videos on my Instructables Channel.

Printed with the X1 Carbon.

Thanks for looking.
