This is a model of a grand piano I made for a friend who has a Yamaha Disklavier. I was amazed at the detail of the soundboard, keyboard, and other things about the piano. I attempted to recreate it here, It features separate white and black keys, a 4 layer soundboard with strings, a functioning keyboard cover, foot pedals and a stool.
I used m3 screws to strengthen the legs (which were rather wobbly without them. and thin wire for the hinge pins - dressmaker pins with the head cut off would work too.
There are some (minor) problems with the files, but I managed to assemble without changes. I did have to use wire for the lid hinge, since the printed one broke off while I was installing the wire. :(
I am including the fusion360 files here as well so you can change it you wish.
Added picture with Canadian(US) Quarter and Euro 50c for scale

Notes:
print stool and legs slow - they are rather thin - I slowed printer after the main body was done.
They 2 part keyboard is a VERY tight fit. If your printer tends to print large adjust the expansion to reduce them.
The strings are VERY SMALL - some slicers will eliminate them if the setting math doesn't work. They are ~1mm wide and 1.2mm tall They also have a top and bottom - use a large brim.
This required a lot of filing and trimming - mostly related to the brims I used. It was also made worse because my printer was misbehaving.
I painted the strings and soundboard, and the pipes for the foot pedals in gold. Its too bright, but not bad. In my print the entire body and lid warped slightly - unsure why.
This was inspired by several models on thingiverse, but I wanted more detail. I also didn't want the keys painted. It was a great learning experience in using Fusion 360 - Freecad just wouldn't do what I wanted - It doesn't like lots of little items repeated.
I started with the keyboard, full 88 keys (I think it lost one along the way - nope!) Then the soundboard, and string support boards. I spent a lot of time on the Yamaha site looking at pictures and dimensions. It is about 1/10th scale, and somewhat accurate - not exact. I'm not good enough for that..... and there are several models.
Several areas still need attention, but overall it should print out ok with some minor fettling and fitting.
The areas still needing attention
keyboard - check layout ok
legs - need better support for printing or make separate - I sanded and glued
foot pedals - slot in base needs to be larger - i filed it.
lid hinge better design needed
clip for soundboard/strings - i glued
