My wife needs to take a pill at 5am everyday. So I made something to help her up.
When she goes to bed, she fills the glass with water and takes the pill out of its blister and put at the top of this pill taking glass. At 5 am, all she needs to do is drinking the water. The pill goes together and she can get back to sleep. The water flows into "water channels" that relays underneath the pill.
I used Natural PLA, so it does look like the glass is bottom less, but this is only a optical illusion. I has a 2mm bottom, that looks completelely transparent at my kitchen counter.
After printing it and showing to some friends, one of them sent me a pictures of a Pill Taker Cup, sold by Amazon. Well... I should have searched before. But, there it is.
