Same here, functional prints are the ones where I have the most fun. Especially when I get to model them myself. Getting into FreeCAD has a learning curve attached but it's worth it, IMO. For me it clicked after I got good enough to not have to ask myself "Can I model this?" but "How long will it take to do it?" I'm by no means a pro but you pick up helpful habits along the way. Here's a tip I wish I had known earlier: It sounds trivial but get into the habit to save often and under a new filename before you attempt an operation where you are unsure of the outcome. It's _very_ easy to paint yourself into a corner in parametric 3D CAD. I use something like this: project-name_ii_rr_author_short_description where ii is a two digit index just counting up from 01 and rr is a revision. The author and revision thing is only really needed in a situation where several people share some responsibilities, like in a company. I name my gcode files similarly but the file names also contain the basic slicing parameters like layer height, infill percentage, support variant. This results in some moderately long file names. The reason I put the (ii) index number as close as possible to the beginning of the name is that most of my printers only display the first few characters of the file name. (Looking at you, Ender 3 Pro!) I'll do my very best to keep you updated.
