Enclosure for Bluetooth Mini Amplifier ZK-502L

Hello all,

since there are some unused wideband speakers (cyburgs needle) shyly standing around in my living room, an experiment came up....less than 10€ for a bluetooth amplifier capable of maybe 2x ~15W and and an ok sound.

Here the link on amazon: https://www.amazon.de/Bluetooth-Verst%C3%A4rker-Audioverst%C3%A4rker-AUX-Eing%C3%A4nge-HiFi-Filter/dp/B0D8KRHJH9/ref=sr_1_2?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=3CZMHWYDLOXKU&dib=eyJ2IjoiMSJ9.PMrZokmzH_UbDivmcqi-LKkqjOhnLbyJDdbxHfGkbsvhPopcJCVWhSIS6SaNLuzijEoso-X0B82Tglkw8WYFw95sA6cVzfMdfoAv7NNu30Of9__sfvrpcrBtNb2E2KXECVe1P0DEn2INflxLdcCvJIdYGtQsM6uPHhzo57hrb_K1gOtF3yZNlag8inS63Tok6P3d8xPCB37oUMfQYEZmb3phX2PuLrme0sZvw2RHn0Q.qFF2uPHjvBvYOzsL9KhBBeRLSlZSJwJk9BjgxyQT1z0&dib_tag=se&keywords=faelink+bluetooth+amplifier&qid=1778595174&sprefix=faelink+bluetooth+amplifier%2Caps%2C105&sr=8-2

On amazon, there are plenty of these devices. A ZK-502L derivate was the one... 8,99€. An old 19.5V laptop powersupply delivers power. Unfortunately, there was no housing available, but a trusty 3d printer was available in the basement.

So, we have a little housing to design and print.

The housing's base and lid are to be attached to each other with some sort of locking mechanism (see picture).

The M2 screws were already delivered with the amp.

For the measurements of the attachment see last picture.

The holes are 3.5mm diameter. The distance between the holes' centerpoints are 33mm x 51mm. The thickness of the tabs are 2.5mm. The optional spacers are 5mm height (hole is 3.5mm diameter as well).

Print settings...as you like...I chose 0.2mm layer height, no supports, no nothing - just throw the pieces on the printerbed, make 1-2 thoughts on print orientation.

Happy printing,

Hannes
