Validate 3D design for a musix box

[jacopo_terri]

Hello everyone.

I want your help validating the design I made for a music box. You can find stl files at the following link https://we.tl/t-sqtMWVbsFU

My idea is to replicate a classic music box shape and update it to make it digital, i.e. reproduce a song and a video through a Raspberry PI. Since this is my first 3d design I have a few things I would like your help for.

1. Display location: the hardest problem I've been facing is about the location of the display. I created a panel and thought of placing it in the box itself. The result is shown below. Do you have any suggestion on where I can place the display?

1. Screw and threds: Is it possible to 3d print screws and threads with a size between 2.0 and 4.0 mm? 

Thanks for your time.

Stl is about the worst file type for evaluating a design.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

(not a link to some 3rd party file storage)

Are all of your sketches fully defined?

It is impossible to manufacture perfect dimension parts - have you included appropriate clearances between mating components?

If you have access to a high-quality printer (probably >30k) you can print 3D threads (the larger size the better). Otherwise you might get away with printing the female threads and chasing with a tap and just purchase the male fasteners.

@TheCADWhisperer I attached the .f3d file.
