I almost exclusively print functional things so here’s my list of things I’ve designed or printed:
Tubular key to bypass paying for laundry
Furniture leg extensions on almost all my furniture to give minimum 4" clearance for the robovac
Custom mounting bracket / spacer for mounting road sign to the wall with command strips
Tapestry mounting shim to clamp tapestry in binder clips to hang on the wall without ripping the tapestry
Rubber band powered sandal holders that stick to the wall and clamp onto sandals which can be used without using your hands / while holding something (I needed to keep my basement sandals from being eaten by my old robovac and I needed to be able to put them on and put them back without needing to put down anything heavy I’m taking to/from the basement, and the space required it to be flat against the wall)
Replacement shelf pegs for bathroom shelves which are normally only sold in 20 packs for >5$ when I only needed 1, the print cost like 1c instead
Replacement D-slotted electrical box key since the one that came with the box broke
Backyard lamp holder that attaches to the fence pole and provides a loop to hang a lamp
Replacement side panel clip for my PC case which came with 1 broken - manufacturer doesn’t sell replacements
Custom piece for 2 sectional couch legs to slot into which keeps the 2 halves of my couch from sliding apart causing someone to fall in between onto the floor
Some of this could have been bought online but having a 3D printer really reveals how overpriced plastic stuff is. I rarely print something that costs me more than a few dollars in filament - and that’s if it’s a very large object, it’s easily less than the shipping cost of an equivalent item alone, and small things can often only be found in large packs online while usually costing only a couple cents to print. And plenty of the stuff I print benefits from being able to be made custom and to the exact dimensions I need, for example the furniture leg extensions I made fit perfectly on the furniture legs and raise them up exactly as high as they need to be for my robovac to go under, not a centimeter more. A whiteboard marker caddy I made holds the exact number of markers I have / want to have and attaches under a light switch wall plate which I designed in order to avoid needing to attach it with command strips or screws (it gets clamped between the wall plate and the wall by the existing light switch screws). The first item I listed, the tubular key, was printed with the exact bitting needed for the lock (layer height of 0.05mm is enough vertical resolution for the key to work).

I would love to see your models. Do you have a printables, thingiverse or something?
Sure, most of them are posted here: https://www.printables.com/@StephenSmith
