I needed a simple way to dispose of sharps from hobby knives, razor blades, box cutter blades, etc for various hobby needs. This fast print gives me a shorter version (80mmx30mmx30mm) for most things or a longer version (110mmx30mmx30mm) which also accommodates long scalpel blades if needed. Once you feel it has served its purpose, it can be safely disposed of. I have used this print for years and never had one break open on me unless intentional force was applied. Prints flat on the build plate with no supports, i typically just use PLA.
