Easter Piigs

I went on a easter egg hunt in the garden and found these 2 beauties. The pink one is mine and the gorgeous light blue Piig is a ‘Sounds & Charge’ shop stock model. If you’re following the blog, you’ll have seen it naked, with holes drilled, to prime, top coat, then final build stage.

The great thing about being a maker, is progress. Every PiigBox I make is better than the previous one. I learn lessons on hole cutting, sanding, priming, and final painting. My 3D printer has become an invaluable tool in making PiigBoxes. From PLA lithium ion cell holders and amp shelf, to flexible TPU speaker grommits which really have are now in version 28 😜…

It was a challenge putting powerful speakers into an ammo can and stop it rattling. So V1 PiigBox had 100mm rubber rings between the speaker and the case. I was never quite happy with them!!!!

So after 27 previous versions (Artistic licence used just a little bit) I settled on a full design which draws the speaker into the case really tightly.

One other flexible 3D printed part you can’t see is the 16 x 1.5mm washers which compress before and after the painted speaker grilles to protect the paintwork.

All of these flexible parts allow me to get the speakers nice and tight and ensure a rattle free experience. Well, until the bass rattles your teeth out……

The next evolution will be a power boost to the amp regardless of pack size (voltage). I have a step up converter in the original PiigBox which steps up from 12v to 18v to give the bluetooth amp a boost. I want to ensure 100% reliability, so need to pressure test a few parts before I make them standard.
