Bottleopener (Push to Open) integrated counter

This bottle opener features an integrated mechanical counter that automatically increments each time you open a bottle.
No electronics, no batteries — just clever mechanics that make every bottle count.

It’s the perfect party gadget: fun, functional, and a great conversation starter. Whether you're keeping track of how many drinks you've opened, competing with friends, or just enjoying the satisfying click of the counter, this opener adds an extra level of interaction to any gathering.

Following parts are needed for the counting Mechanism:

1x compression spring

1x M3x16

Depending on the Version you want to make you need the following parts:

Printed Version:

And for the opener itself:

1x M3x8 (For the rubber bands)

1x M3x12 (Connect the two lever parts

2x M3x16 (for the Lifting mechanism to strengthen the opener)

1x M3x20 (to keep the two lever parts fixed in the outer part)

1-2x rubber band

Screw the 8mm screw into the top part. Connect both parts with the 12mm screw. The two 16mm screws arescrewed into the lift mechanism until they cant go deeper.

Insert the Lever into the housing and fix it with the 20mmscrew.

Wrap the rubber bands around the screw from the lever and the attachment point of the housing.

Conversion Kit:

Due to the fact that 3D printed parts are not that reliable I tried to convert a existing push opener into a 3D printed version. To use the metal mechanism is much more reliable than the 3D printed version. 

I tried to find a supplier that could provide this individual parts to make building this version easier, but unfortunately they only sell complete bottle openers. If someone is interested to make a real product of this please contact me.
