I started printing in April this year. Got myself an Ender 3 V2. I've done some light mods, but nothing like direct drive or dual Z.
Here are some of the things I've printed that have been useful. Titles are hyperlinks to Thingiverse. All items are eSun PLA+, except for the blue stuff (watering can, printer mods). Those are all done with eSun Silk PLA.
Bag seal clips
Probably the most used thing I've printed. We use these for everything. Cereal bag, biscuit packs, crisp (chip) packs, bread, rolls, frozen stuff like peas, corn etc, and any other pack that needs a good seal.
Also designed a simple holder for them to store when not in use. I added a couple of recesses in the back and glued a couple of magnets on there. It sits on the side of our fridge in a handy location to grab them.
It sits next to a simple paper napkin holder that I also designed with some magnets on the back.
Reindeer
I printed these reindeer for Christmas. Simple but very effective!
Watering Can
I printed this small watering can for my wife's library/styudy room, for watering the plants she has in there. It's a perfect size. Something I'm very happy with!
Autorewind Filament Spool
This is an auto rewind for my filament spools. I keep my rolls of filament in a drybox. It's a pain having to feed the filament back in when changing colurs. So this winds the filament back onto the roll. It's designed so that it will wind up the internal springs until they are tight. But if you keep using/feeding filament past that point, it just slips, like a clutch type mechanism, so that it doesn't overwind. It's a genious design, and I'm really happy with how they came out. It took a bit of tweaking to be able to print the springs cleanly. But having done that, my printer is now working better than ever!
Can holder/dispenser
I printed this can holder for the fridge just recently. It's obviously printed in sections, which lock (and glue) together. It's fantastic!
Parts Drawers
I printed a load of drawers for various bits and peices, like screws, nuts, bolts, small tools, printer parts etc. They can stack in any configuration you want. I need to shift that shelf lower, which is why I haven't put the drawers all together yet.
What I love about these is there's a hidden magnet on the back of each drawer, and back of each housing. So the drawers lightly pull/snap closed when you push them in. Gives a nice premium feel
Sidecutters Grips
I printed a new set of grips for my snips. Every Ender owner will know about this

. These snips come with the printer, but the rubber grips don't last too long!
Dremel Mount
This reallly comes in handy for some jobs. Holds the Dremel firmly in palce while using it.
This is something I started designing. A holder/charger for my Note 20 Ultra, Gear S3 and Galaxy Buds. All custom designed to fit those specific products, with the cables all hidden in recesses underneath. It needs more tweaking though, and I haven't had time to finish it yet. (the back is snapped off the phone part)
And this is my setup. Bit messy at the moment, as I'm still shifting stuff around onto the shelves. But it's where I do my printing, and other tinkering/fixing/playing
And the printer itself. I've toyed with a few different fan ducts. Had Bullseye on it for a while, but printed Satsana Mini yesterday and am trying it out.
Other things custom are the
cable chains,
camera mount/arm,
extrusion inserts, display button, drawer handle (designed myself)....those are the main things. I plan to upgrade to larger/more silent fans all round, sometime soon.
