KeyPop - Key Cover Bottle Opener

Inspired by the community and now for the community comes the KeyPop – the key cover bottle opener.

Boost MeIf you like my work, support me with a boost. It’s free for you, and it means a whole lot to me.

 

Recommendation: Print it with PLA Tough, normal PLA will break eventually by use. I also recommend using the the hand position when opening a bottle shown in the picture further down below for using the KeyPop.

 

For this model, I was inspired by the community, and I would also like to inspire others to take the idea further and improve it. Feel free to take the model, enhance it, upload it for others, and let it inspire them as well. 

 

The KeyPop in this STL is designed for a small key, such as one for a padlock or a bike lock. It’s meant for a key you don’t use very often but usually carry with you. The KeyPop cannot be removed from the key in order to ensure stability, so it should really only be used with a key you don’t need frequently.

 

The keydisc embedded in the KeyPop has the dimensions 20.5 mm x 20 mm x 2 mm, and the opening for the actual part of the key below the disc has a width of 9 mm. However, I see no reason why the KeyPop shouldn’t also work with larger keys or even with square-shaped keys. For this, you only need to adjust the cavity inside the KeyPop to fit the key you want to use.

 

 

How to use the KeyPop to open a bottle

To open a bottle with the KeyPop, the force for the lever movement should not be applied to the key itself by the hand, but rather to the KeyPop. For this, I recommend the hand position shown in the picture.

 

Printing the KeyPop

The KeyPop basically is just one 3D-printed part, and the key is inserted into the KeyPop during the printing process. For this, a pause is added in the slicer at the top layer of the cavity for the key. Then the key is placed inside, and the print is continued.

The pause is inserted into the 3MF file at the correct layer. This one was printed with a layer height of 0.28 mm and 15% infill in a grid pattern. In the 3MF file, I have now adjusted the infill to 100% for better stability. However, with 15% infill it also worked perfectly for me.

 

Cheers!
