Water bottle drinking lid

Having found no suitable drinking attachment for the Holy glass bottle to date, I had to help myself.

The bottle is nice, but it's difficult (for me) to drink from the large opening; also, I wanted to avoid any mess if the bottle were to fall over (onto a desk, laptop...).

Constantly screwing the original cap on and off just for a small sip was too cumbersome for me; then I left it open – and thought to myself that a bottle with such a large opening could also lead to a big mess.

The model includes an attachable sieve; this serves to improve stirring or shaking to mix the powder more evenly into the water.

The sieve is

*** Assembly information ***

Attach the TPU sealing rings to the inner part as shown in the pictures.

It is best to carefully widen the rings slightly and start from the bottom.

Then carefully insert the inner part into the lid and, using a little feeling and a small slotted screwdriver, help the seals to get past the edge.

Insert the main seals into the lid.

Snap in the sieve.

*** Parts information ***

All parts are printable; however, if you prefer O-rings for the screw cap or have some at home, these should be the two.

This week Aldi had an O-ring assortment:
O-ring 1: 40x3.55 (R-28) [40mm inner diameter, 3.55mm thickness]
O-ring 2: 31.5x3.55 (R-23) [31.5mm inner diameter, 3.55mm thickness]

*** Note *** 

This closure is not 100% leakproof; it can happen that it drips if you hold it upside down or shake it.

Not suitable for highly carbonated drinks.

For suggestions and optimization ideas, feel free to write – I also look forward to feedback.
