The drop spindles I make must be glued. They can’t be taken apart for flat shipping. To protect against having them crushed during shipment, I created cardboard spacers that fit in the clear plastic box. They keep the spindle in place, and allow for fiber to be shipped along with the spindle. It’s a nice way to present an object to the purchaser.
Being the person who uses what’s at hand, I used a shipping box from amazon. The cardboard is .11" thick. I was in a hurry, so I didn’t mask before I made my cuts. I’m glad I didn’t because it wasn’t needed. The pieces came out very clean with no smoke residue.

The center piece has a hole just larger than the spindle shaft. The top and bottom pieces just have an “X” cut, since it’s not necessary or desirable for the ends to protrude. I did want them locked in place, though.
