The file 'Straw Case Box With Sliding Door – Laser Cutter' is (cdr,pdf) file type, size is 1.8MB.
I got a pyrex drinking straw, and while it's probably tougher than this case, at least now it doesn't bounce around in my bag; clinkety clink.
Fits a 20 x 1 cm~ straw.
Cut from 1/8th of an inch hardboard.
