My parents are visiting at the moment, and I wanted to print them some useful things that they could use. My dad needed a shoe horn, so I found this one that fits the bill, and it printed very nicely. The weight feels good and it's just the right width.

My mom wanted a picture frame that could go on the fridge using magnets. I found this OpenSCAD design that is easily customisable, so I was able to create exactly the size and frame width that I wanted. Printing large flat things can be tricky on a 3D printer, but the i3 MK3 handled it quite well - I just had to use the optimal settings instead of the fast settings.
