Description

A gripper style nutcracker with a print-in-place hinge.
Works very well, easy print and no hassle break-free.

Please don't use the old print profiles anymore! Use the new ones!

2025-03-27: I uploaded new print profiles, one with a joint inside and
another with an joint outside. Both joints are bigger and has little more play.
First it is easier to break free and it is more robust. The grip was also made a little bit
thicker on the end. With PLA-CF it has few flex.

Please leave a comment, print profile rating and pictures.

Have a look on my other models.

Maybe try the print profile (model) with the inner joint?

Printed in PLA - 7walls. Kept flexing and totally smashing the nuts. Then I tried a different position of nuts (see the picture) and this works. I've crack-openned many hazelnuts and it keeps working, didn't break.

Moderate force should break it free. Therefore calibration of the printer and filament is so important. Hope it works well for you.

Nice model, printed fine. As to the intended use, it has quite a bit of flex (printed in PLA), but it works. The edges could be a bit more rounded to be more comfortable in hand.

Thank you for the feedback. But it does not look broken? All critics is known. I will work on a better version as soon I have time and nuts. Then I will adress * the flex * rounding on the handle (as long no support is needed) * surface of the joint But so far I cracked a lot of nuts with that piece. I am surpriced myself it lasts that long.

Very good model I set wall lines to 7 and a very high infill density inside the part so that it is very strong and for now it works very well

I tried it with PETG, because with such a model I assume it will not hold up during later use. 120mm/s + 85% infill = 9h print time....... I was never able to use the part because it is designed too tightly and the joint sticks together -> it broke at the joint during disassembly

I have never printed it in PETG, nor have I ever recommended it. The text clearly states which filaments I successfully used to print the nutcracker (many, many times). After printing, the part must cool down, and then the joint can be broken free. Which one did you actually print? Joint inside or outside? The models are different - not just the names. I can upload another model with a larger clearance.

Replying to @don_manfredo :

I had printed it with "joint outside". Thank you for the offer of more clearance, but you don't need to do that for me anymore. As a proof of concept model, it is quite interesting, but I don't want to invest any more material and energy and will simply buy a nutcracker in the 1-€ shop

Replying to @Sproove :

I didn't have a nutcracker over the weekend. Therefore, it was intended as a makeshift solution, which has proven to be practical. I will adjust and upload this in the next few days... and of course print it
