I can’t compare it to the cad examples but meshmixer is definitely easier to use for small stl edits than blender, especially for things like cutting and keying parts. If you are just trying to make a pin smaller or hole larger, editing the xyz of specific points in blender may be easier depending on shape. Good luck!

I was in a simiar boat, but once I started learning it really took off and I couldn’t find enough things to model/fix! I started with meshmixer, it’s pretty simplified but still somewhat powerful and I think Windows only. Once I found stuff I couldn’t do with it I switched to blender and now I’m much faster with it. I found there are some things each implements better so if having an issue I’ll switch and try something else. I highly recommend picking one and watching youtube videos specific to what you want to change in a model

Edit: you may be able to get by on some of the connectors by lowering flow too, depends on how dialed in your printer is, everyone needs different tolerances

It drives me crazy that notes does not reorganize the list when you check things, but that’s probably because it’s just markdown. My wife also refuses to use it. Carnet is the google keep like alternative that I think would work for me, but the sharing isn’t working currently, whenever the note is updated the share is removed.

This is the exact opposite of my experience. We’ve been using codium in my org and 9/10 times it’s garbage and they will not allow anything that is not on prem. I’m pretty consistently getting recommendations for methods that don’t exist, invalid class names, things that look like the wrong language, etc. To get the recommendations I have to cancel out of auto complete, which is often times much better. It seems like it can make up for someone who doesn’t have good workflows, shortcuts and a premium ide, but otherwise it’s been a waste of time and money.
