Compact and universal shower/faucet

Compact, lightweight, and convenient, it quickly transforms any container into a refreshing washing tool. Perfect for hikers and campers: just screw it onto a bottle and enjoy a gentle water flow anywhere.

How to use it

Screw on the bottle like a regular cap. Four protrusions on the top part will help you. (Don't overdo it, if you have a bad sintering of plastic, the thread will break off)

The lower part with holes has a left-hand thread, so to increase the flow of liquid, you need to turn clockwise.

The different direction of the thread allows you to avoid biting the parts.

Bottle neck compatible

After analyzing which bottle necks are mainly used for bottles in my country, I decided to use these threads:

1. PCO/BPF (outer diameter - 28mm, 1 start)
2. Bericap 38 (outer diameter - 38mm, 3 start)
3. Bericap 48 (outer diameter - 48mm, 3 start)

Versions

V1.5 - I printed it and it works well.

Down V1.6 - Reduced the number of holes, as there was too much liquid flow on V1.5, compatible with Up V1.5 (Not yet tested).

Printing:

Material - PETG (or any other)

Layer Height - 0,2mm 

Infill - 100%

Also make the seams inside, or make sure that they do not bulge on the thread and the central hole.

P.S. The tightness is not perfect. I also think that the thread is not the best way to regulate the flow, perhaps I will make a version on the clip.
