Confuse your friends and confound your enemies when you challenge them to unlock the compartment to reach their prize. This lockbox is a perfect prop for role playing sessions, escape rooms, party games, or as a fun display piece.

The inner storage chamber is a cylinder over 2" (~60mm) in diameter and approximately 4" (~100mm) tall, perfect for storing gift cards and other sweet surprises.

It's easy to reset or change your code when the lockbox is unlocked; just don't forget your code! There's no easy way to open the lockbox without it...

What is inside?

This lockbox is sold as a kit of .stl files, with the final build consisting of over a dozen pieces and parts that must be assembled together. A digital parts / assembly / printing .pdf guide is included to help walk you through the assembly process.

How is it printed?

The largest parts in this kit require a print volume of at least 155x155x135mm in dimension. Your 3D printer should be properly configured and "dialed in" to print fine lines accurately, as some of the parts include 3D printed screw threads.

All of the provided .stl files are prearranged to import into your slicer in the proper orientation. Supports are not required for any of the parts in this kit, though you may want to paint on a few to support the ceilings of the screw threads for the top connector. Glue is also optional when assembling the top of the egg; any super glue or 3D modeling glue will suffice. See the assembly guide for more information on both of these topics.

Was it test printed?

Yes! The complete lockbox was printed on a Prusa XL using the standard Prusaslicer 0.15mm speed profile with various types of Polymaker PLA. Using the recommended printing settings, the final single-color assembled print weighs in at just under 2lbs pound (just about 1kg) and took approximately 30 hours to complete. The dual-color variant weighs approximately the same but takes almost 50 hours to print. Weight and print time will vary depending on your own specific setup.

Boring Legal Stuff

Like all of our designs at Hamilton PrintWorks, this lockbox design is an original work protected under copyright law and the lockbox model itself bears the HPW logo (where feasible). While you can make minor modifications to the models to aid in printing the parts themselves, the HPW logo must never be removed.

Purchasing this digital kit grants you a non-commercial personal-use license allowing you to print the lockbox for your own use. The digital files are never to be sold, shared, given away, or distributed in any way, nor are derivative works to be made from them without our consent.
