Update 2025-10-21: After using the corkscrew for a few months I found that the small/short support is not robust enough. It bends too quickly. That is why I modified the bigger support so it gives more hold to the small one. Have a look at the “support modified” stl

After having used my previous design ( [https://www.printables.com/model/1237460-a-better-corkscrew](https://www.printables.com/model/1237460-a-better-corkscrew)  ) for a while, I came up with some improvements.

1) The handle is wider and stronger
2) The handle is longer and therefor you need less force to get the cork out.
3) The supports are now centred and thicker, what improved the stability and strength.
4) I changed the way on how to get out the supports out of the handle. It makes the handle sturdier because the indent is not so big anymore.
5) The commercial corkscrew I disassembled, to get the metal screw, also had a blade to cut the seal of a bottle of wine. I integrated this blade in the design. When you do not have such a blade, I also uploaded a design with no space for such a blade.
6) It will now also accommodate slightly bigger corkscrews.

For strength print it as shown in the 3mf file.
It is best to print it with 1.5 mm layer height. 15% infill. I used PETG
You can use the 1.8 mm holes, after reaming, to align and glue the handle halves. This is not really needed anymore, the three screws align the halves also pretty good, the little filament pieces do a better job in alignment though.
You need now 3 times M3 X 20mm flathead screws.

As always:
when you print this model, post a make and some pictures,
when you like it give me some hearts and likes, it is the only reward I get.
when you have questions just ask.

Below the original text:

When you are a waiter, and still crafty, you probably daily use the traditional corkscrew where you hold the bottle with one hand, screw it in the cork and press the lever upwards.
This is OK when you have to open the bottle next to the table.
However when you have the possibility to place the bottle on the table, my version is easier to use and requires less force. See the explanation below.

The idea is not new.
A few years ago I bought such a type of corkscrew. Unfortunately I cannot find it anymore, so I recreated it by designing my own model. 
There are two supports, short and long in my model. You likely start by using the short one pulling out the cork as far as possible and then switch to the long one to remove the cork completely.

The most “difficult” part is to find the metal screw. For this I disassembled an old one from my kitchen, and designed around it. When you print this design you have to find a screw that is approximately similar in size. The dimensions of the screw I used are in a drawing.

Further you need 3 M3 X 20 flat headed screws. I used self locking nuts. When you use normal M3 nuts, you likely need a drop of Loctite.

It is best to print it with 1.5 mm layer height. 15% infill. I used PETG. 
After printing you have to ream/clean the holes with a 1.8 mm and a 3.2 mm drill bit.
The 4 times 1.8 mm holes are for alignment during glueing the two handle parts together. Just insert small pieces of filament (max 6 mm long), add some glue and clamp the parts together.
