I decided to create this design after watching my wife dealing with used insulin needles. The idea is to provide a more practical way to keep the needles before sending them to the proper disposal.
It consists of a box with a cover and a lid. The cover is intended to facilitate the removal of the needles for disposal. The lid is for daily usage for easy access to the bin.
It has a wall support that is used to hang it everywhere. The support can be attached with double-sided tape or with bolts. You may also lay it on a flat surface.
I'm not mainly a fan of printing parts in the same direction the efforts are applied. That is why you will notice that handle and hinges are printed as separate parts that shall be attached later through some unique grooves. It is better to use some glue to keep them in place.
For the hinge pin, I used an M3 bolt with a self-locking nut.
The biohazard logo was printed with two printing steps and different filament colors. You can also print it in one color, and late apply some paint or not. It is up to you.
In order to facilitate any changes in the design, I have also included the Fusion 3D file of the complete assembling. Use it as much as you want.
