This is a 3d printable design which can house different electronic circuit boards. In its standard size it can house a 70mm x 100mm PCB.
Top and bottom halves of the boxes are identical. There is only one STL file for the box and it can be used both as the bottom or the top halve. There are many vents and holes to cool the interior electronics. There is also a simpler version without the holes & vents.
This product and project is aimed to be used in vehicles for generating turbo and various other sound effects.
Read more for downloading the product case STL files for 3d printing, CCS C source codes, Proteus simulation, circuit schematic and PCB layout files and also 70 different sound effects I’ve found on the net and especially prepared for this project.
I’d published a product for mounting mp3 players to bikes some months ago. Recently I’ve resized it, converted its locking mechanism to a double lock for added strength and printed one, by using an UP printer. I’ve assembled it to my folding bike with the mp3 player that i’ve bought from the market for just 14$. The design turned out to be nice, performed its duty well, holding the mp3 player in place at the same time directing its sounds towards the rider. Though the speakers of the player were at the sides, the sound was being distributed to the sides and music was a bit difficult to hear without redirection.
now sound is good. The STL files are at the end of the article for the ones who want to print their own product.
