Those are the best printed out of shore hardness A95 TPU, I recommend to dry the TPU well - before use, and select avoid crossing parameters for the best results, its also important to print this will cooling fans on to avoid melting.
Print one part at the time to avoid stringing.
The handle grip should be printed from softer rubber like 90A or 85A but its up to you
We also treat the prints with ESD coating before releasing those to production.
An implementation of those - can improve safety of use and storage of popular scalpel knives in production environment
