Pepper grinder cap

This is a cap for those disposable pepper grinders to allow refills.  The disposable Kirkland pepper grinders we get at Costco last a while.  Unfortunately, it's not possible to refill them.  This cap allows sealing the container after refilling.  To drill the hole, we first used up all the pepper and then slowly drilled a hole at the top.  The hole is approximately 11mm (7/16") in diameter.  We used a hobby knife to cut away the excess plastic and enlarge the hole as needed.  We were able to get any plastic bits out after we were done.  It's worked well for over two years.

Printed in PETG with 4mm perimeters (top, bottom, sides).  No supports needed.
