you need:

4 wooden rods with a diameter of 4mm and a lenght of:
2x 19mm
2x 16mm

4 screws (just see what screws roughly fit)

2 rubberbands (there should be tention on the mechanism at all times)

Acrylic Tube with an outer diameter of 120mm and an inner of 114mm (you can choose the lenght of the tube. i choose 250mm in the video)

if you want to you can add a rubber ring on the lid. (either print the file i added in TPU or buy one that fits)

the rubber bands are a bit hard to fiddle in on this version, i am sorry about that. (you can see some footage in the video)
