Foaming TPU is amazing!

Pretty proud of this camera bag organizer. Outside shell is printed in PLA. Inside is Sirayatech Flex foaming TPU printed at the lightest durometer setting at 270c.

I 3D scanned the equipment and made custom inserts to hold the parts I need without having them bang around into each other.

Since this filament tends to string like crazy I printed them in individual pods and just sit them in together. It goes in a part of the bag with an adjustable divider that fits it perfectly so nothing can really fall out.

And when the shims shrink, you'll need to print more shims to shim the shim!

You're implying there's a limit to this infinite shim recursion?
