The model is a large solid bottle. You need to scale it down to 25mm in the Z axis (height) in the slicer before printing.
I made the object myself, following a fusion 360 tutorial.
Print in vase mode (spiral mode) to make it hollow. The neck of the bottle fits into the hand with the hole.
I printed the ones in the photo with cheap transparent PLA from Geeetech.
The author remixed this model.
This is another accessory for your thirsty Dummy 13.
