Harry Potter's Musical Trunk

I became interested in printing a music box when I purchased my PS1 and was gifted the K-014 kit. I printed the Grand Piano and it was very nice.  I did want to create a box that would start and stop with the opening and closing of the lid.  I decided to model my box after the trunks that were used by the Hogwarts students in the Harry Potter movies.  The trunk has the Hogwarts logo on its top and for those people who want to personalize their trunks I created decals which can be glued on. Also there are labels which can be applied to show which house you belong too. 

I included two print profiles for the  trunks they are 0.16 and 0.2 layer heights, both are printed with 4 walls and 20% infill and they functioned the same.  All other items, hinges, hasp and “decals” printed at 0.12 layer height to provide the desired detail. I developed the hinges and the hasp myself and they were strong enough when printing with Bambu basic PLA.  I did print one box with Amolen Silk PLA and the box was fine, except for a little lifting on two of the corners, if i printed it again I would use something to help with the hold the print to the plate.  Every print with the Bambu Basic PLA was perfect.  Other problem with  the silk PLA was that one of my hinges broke. Not a problem I just reprinted them with  the Bambu PLA.

I printed a plate to go into the lip to cover up where the supports were.  You can print this any color youn desire, but I bought some mirror adhesive sheets on Amazon the  applied it to the plate and the results were pleasing. See the pictures.

The trunk is compatible with Makers Supply Piano Music box kit K-014.  The shut off mechanism came initially from a device I bought from Music Box Attic and I customized it to fit my trunk.  Problem was there was no way to purchase this device. I found another cut off device on Amazon that actually fits much better, Creative Hobbies E240 Spring Loaded Plunger. I fastened  the box to my trunk and then cut the wire to fit the plunger I designed and it worked than my first attempt.

I am new to designing and learning my around the CAD programing, this was a fun challenge to take  on and I hope you may enjoy it as well!
