This was the ULTIMATE Gag-Gift for a family member who has a new German Shepherd!

From the original Potty Bank (Thankyou 3dPrintingWorld for the original design!):
I scaled it up 315%
Then used Meshmixer to subtract a 90mm cylinder from where the coin slot is, to accept a standard 1.25lt water/soda bottle.
Smoothed using Meshmixer.

Also made two bottle adapters - one to have the water level at the lower lip, and one for the water mid-way up the lip.
Then made the lid pin.

Notes if you want to make this yourself:
You will need a 400mm cubed print volume! The main body is just under that and all one piece! No supports needed.
I have included the original lid - scale this up by 315% in your favorite slicer program.
You will more than likely need a 2kg roll of white (whatever material you choose! Yes, talking to you - argumentative people about different 'food safe' plastics). I used just under 1.5kg for the main print.
The bottle adapters are quite hard to get in, but remember to keep the chamfered bottoms to the back, squeeze the two sides together and push it up from the bottom of the bowl.
Make sure your water bottle is 90mm diameter or slightly less.
Print the pin flat down. Support may be needed for this.

I printed this with Spectrum PLA - Polar White - 1.75mm - 2kg Spool
And a wood filament for the lid.
I used 4 walls, 5/6 top and bottom layers, and 5-8% infill.

NOTE: Due to the comments I have been receiving, I can't believe it's necessary to say this...
I am only supplying the CAD files here!
I DO NOT CARE if you 3D print this out of plastic, concrete, chocolate, ceramic, carbon fiber, steel, dog poop, etc!
If YOU want to make this, then YOU take the appropriate thought and actions!
I personally made this as A GAG-GIFT!
Not intended for long-term use! The recipient knows this!

Other than that, Enjoy!
