i played a few of these bartops. they were intentionally very hard for short playtimes, and were a bit too expensive too play a lot. it kinda seemed like it was there to get money very few times out of very few people.
as a huge nerd who plays games at bars, the bartops were not good, heh. barcades and pinball halls are much more fun.
people mostly follow the 3-months/3k-miles rule. i once left oil in there for ~8 years and didnt notice a difference, but that will probably be ill-advised by many on here.
thankfully, i drive an ev now so i dont need to maintain (or... not maintain in this case) oil changes.
you mentioned CAD was a bit too much for what you are looking for; however, there is a simple code-only cad program that makes simple tasks like making a shape super easy: openscad
i think i am old. i grew up using DOS, and really hated spaces in filenames and folders because they appreared truncated at the first space with a tilde and index of that file/folder representation.
ex: C:\folder name is bad\ == C:\folder~1
i hated that so much that when i got to windows 3.1 i refrained from using spaces (some command line was still necessary in w3.1)
i have jept that habit through the years, so when i moved from windoes to linux, my natural instincts of snake_case_folder_names made it so i didnt have to change : D
my work has an english only rule when talking about work. we hire from all over the world, so making sure there is a common language is nice when i have to message someone in another country.
i can imagine the unimportant meetings that werent part of the show... you know like routine runs.
"i am captain jean luc picard of the USS Enterprise. to my right is my number one, commander riker. to my front left is my number two, lieutenant commander data... as opposed to this random lady sitting next to me who has nothing to do with leadership on the bridge."
i am a very late bloomer to ST. i watches TOS and loved it; i startrd up TNG about a month ago.
im in season 3 episode 4 and councillor troy hasnt died yet. i hate her with a fiery passion for ruining what seems to be a really good show. my friends have confirmed she doesnt die and told me to leave TNG behind and move on to DS9.
EV + solar panels on my house == free charging. i am so happy with this combo.
