“I bought the ninja diffuser layer to use on top of a Ninja Pibow with a Unicorn Hat HD.
It's just like the diffuser supplied with the Unicorn Hat, but bigger and the nuts/bolts don't obstruct the view to the pixels from some angles.
The only thing that would make this purchase better is if this layer came with 4 black bolts to look nicer and not stand out so much (I sprayed mine with black matte paint). It's only natural to have those since the small Unicorn Hat diffuser comes with black ones already (the short metal ones).”
“The ninja diffuser is a functional piece of equipment meant to soften the intensive light coming from an Unicorn HAT, for example. Also it looks perfect on the Ninja Pibow Case. Now all I'd like is a Ninja bottom like that. :)”
“As others have said the LEGO layer is a well built addition to the Pi but it is a bit of a let down that it is quite tricky to attach any kind of larger LEGO brick to the underside of the build. You can get around it with a layer of two of 1x2 plates (which also helps get past the locking nuts) but it would be better if you could easily attach the larger pieces of LEGO in your collection.”
“Each of these options for expanding and repurposing the pibow case design to something else is a great way to avoid having to buy another case.
Just make sure you read all the details for any option you consider buying.
The extension layer is just one, despite the photo showing a few on top of a pibow chassis. Even a single one does require longer bolts on a full height pibow.”
