There are a lot of brands of sewing needles, and they come in many different types of packages. This makes storing them neatly a challenge. Unable to keep track of which ones I had, and which ones I needed, I cracked and measured all the different types I have. The card packaging of the Organ needles is the widest (John James is the tallest), so wide that I realised that if I make the width just a little bigger I could fit two of the more standardised plastic packs side by side. It came out to each slot being 72mm x 8mm X 30mm.

Which fits;
Klasse
Prym
Schmetz
John James
Organ
Lapwing

In 3D Builder I made ten of this shape, arranged in a grid with 4mm walls between and around each, and subtracted them from a larger block (maintaining the wall widths). Then I printed the result. I had massive problems with the PLA filament I was trying to use. In the end I scrapped* the entire roll and went back to my reliable black PETG.

(* scrapped in that, I'm going to find a way to use it outside of my printer, probably following these ideas; 'Can 3D Printing WASTE be Recycled at Home?' by the Brothers Make)
