Box for cradle knives

German

• Upon recently acquiring a cradle knife, I immediately pondered safe storage preventing accidental contact with the extremely sharp blades.
• I promptly embarked on designing a straightforward, space-efficient solution, surpassing the safety offered by the existing plastic sheaths.
• Simultaneously, I aimed for an easily printable design, integrating hinges for both case halves and the locking mechanism, eliminating assembly.
• Standard hinges rely on axles, susceptible to breakage under mishandling. Therefore, I opted for small hemispheres, providing a more robust connection.
• Only the locking mechanism necessitates support, unfortunately leaving unsightly marks requiring post-processing.

• Consequently, I subsequently printed this mechanism separately, oriented vertically. The required support then only affects one side.

   

• Those wishing to print the mechanism separately can remove it from the print bed; the parts are defined as individual objects. The two case halves remain print-in-place. A separate print bed is provided for the mechanism.

   

• Assembly

  • Assembly is only required if the locking mechanism is printed separately. The mechanism can be firmly pressed into the hinge.

     

• Material

  • As the box is intended for food-related use, dishwasher safety is crucial. PLA is unsuitable; PETG or ASA/ABS are recommended. PETG is preferred due to its easier printability.

     

English

• When I recently got my hands on a cradle knife, I immediately asked myself how it could be stored in such a way that the really sharp blades could not be reached into accidentally.
• I immediately set about finding a simple and reasonably space-saving solution that would be safer than the two plastic covers still in place.
• At the same time, I had the incentive to develop an easy-to-print solution in which the hinges for the two halves of the housing and the locking mechanism could be printed at the same time without the need for assembly.
• Conventional hinges work with axles, but these are at risk of breaking if handled incorrectly. I therefore decided to use small hemispheres to provide the connection instead of an axle.
• Only the closing mechanism requires support, which unfortunately leaves unsightly marks that have to be reworked.

• That's why I printed this mechanism again separately, but standing on its side. The support that is then also required only shows its traces on one side.

   

• If you also want to print the mechanism individually, you can delete it from the print bed, as the parts are defined individually as objects. The two housing half-shells are then still printed print-in-place. There is a separate print bed for the mechanism.

   

• Assembly

  • Assembly is only necessary if the locking mechanism has been printed individually. The mechanism can simply be pressed into the hinge with a little force.

   

• Material

  • As the box is used in the food sector, it should be dishwasher-safe. PLA is NOT suitable for this, rather PETG or ASA/ABS. PETG is my recommendation because it is easier to print.
