Description
You know models can be licensed, but not ideas.....
This 3D-printed letter opener / package opener is a simple but practical desk tool designed to open letters, envelopes, and small packages quickly and safely.
The handle features a honeycomb structure, which keeps the tool lightweight while maintaining strength. The hexagonal finger grip provides a comfortable hold and improves control when cutting open mail.
The slim tip easily slides under envelope flaps or tape seams, making it ideal for daily use at home, in the office, or in workshops where packages arrive frequently.
Because the model is compact, it prints fast and with very little filament, making it a great quick print or a useful addition to any desk organizer setup.
The design also prints without supports and works well with most common filaments like PLA or PETG.
Perfect for makers who like practical prints!
