- It is recommended to print around 30 mm/s with a 100% infill
- Orient the two printed pieces so that:
- The holes align

- Locking wedges are pointing toward each other for proper engagement
- Insert bolt into hole. (Direction does not matter)
- Engage the nut onto the bolt.
- Tighten with very little force using a screw driver and a wrench. (Over tightening will the limit the ability of the hemostats.
Common Problems and Solutions
- Make sure that the wedges that lock into each other are both wide enough and deep enough so that they do not break when you try and lock the Hemostats down.
- Make sure the nut & bolt are loose enough to allow free movement of the hemostats.
- Make sure the all of the pieces are thick enough as to not bend under forces (minimum of 4mm thickness is recommended)
