This is a model of a manual hand cranked music box with engraved wodden box. The model has been s_caled ten times (x10)_ for better renders but all the parts are made to proportion.
The meshes using PBR materials are UV unwrapped.
The drum is set for Tears in heaven by Eric Clapton. It can also easily be modified to any other song (4 bars 4/4 or ~12 seconds) with just a little tweaking in the [.blend] file.
The diaphragm (metal pins) have set shape keys for easy animation.
The engravings on the box are made using [.png]s and a normal map for easy customization. You can create your own normal/bump maps and pngs make your own engravings. Just need to change the filename in the material.
A [Read me] has also been inculded for details on gear + crank timing, modifying the drum for other songs and creating custom normal maps. I'll try my best and help you set the instrument for a different song too.
Please leave a like or review if you like the model :)
