After dropping my battery charger a few times, it was time to make a case for it :)
Simple case for this excellent power bank.
Power bank was bought on aliexpress.com
I have been interested 3D, since seeing Lightwave3D on the Amiga computer some years ago.
Its only until recently I actually made a 3D model....Thanks to 3D printing; software has improved for creating objects.
I use Fusion360 at the moment.
