I myself have made a couple of very simple watertight (non essential) prints for scubadiving. They are holding up really well!
The guys from Prusa Research have a lenghty blog post about watertight 3d-prints: https://blog.prusa3d.com/watertight-3d-printing-part-2_53638/ This might be a good source for tipps and tricks!
I am currently playing "It takes two" together with my wife. It looks cute, has a story that is funny and really sad at the same time and the mechanics of the game change frequently. The occasional (optional) Minigames are really fun too!
I have another one:Me: "How old are you?"Her: shows two fingersMe: "Yes, you are two..."Her: "I'm a number!"
Translated:"I need my pacifier!" no reaction from the adults because we want to use it less "... it was just a proposal."That made us laugh because it was so unexpected to hear a two year old kid say this.
I mowed the lawn and got rid of a whole lot of weeds.I learned (sucessfully) to permanently mount my network drives in Linux.I went diving in a really murky lake but enjoyed it.I played a very intense session of DnD with friends.I played some games on the computer.Wow, what a great week!
I turned on the "wrong water" in the shower. (?)
