Description

This is a symmetrical gravity knife-style model designed for demonstration and fidget purposes. Both sides feature the same rotating mechanism, connected by internal gears that synchronize their movement.

 

HOW TO ASSEMBLE

Instead of a blade, the model includes a slot designed to hold a key insert, making it safe and practical as a display piece or functional accessory. To get this blade piece onto the rail, you must pause the print(the print profile added has the pause programmed, and insert the blade piece(the smallest one) onto the rail, and resume the print. After printing, you can assemble the handles. The handles lock smoothly into place with a satisfying snap action, providing a realistic and mechanical feel.

 

This model is perfect for showcasing motion design, gear synchronization, and mechanical precision in your prints. Happy printing!
