Power Rangers: White Dino Sword
The White Drago Sword from Power Rangers Dino Thunder, motorised: the blade extends and retracts on command.

The White Drago Sword from Power Rangers Dino Thunder, built as a commission replica with a blade that extends and retracts like the in-universe weapon. Roughly 65cm stowed, roughly 78cm extended.
Getting that action right meant a linear motor system and a 3D-printed rail mechanism, all fitting inside a slim-line sword body without turning fragile or heavy.
A built-in lithium-ion battery powers the mechanism, charged over USB-C through a stealthily placed port, and a two-way switch gives full control of extension and retraction. Printed in colour, under 2kg in the hand.
Development
Yet another project that brought a new design and engineering challenge into my life! This time, the client simply wanted a replica of the White Drago Sword from the TV series Power Rangers Dino Thunder...
However, the challenge came due to them wanting the sword to be accurate to the in-universe weapon. Which means that the blade needed to be able to extend and retract on command.
Therefore, I needed to figure out the engineering behind a linear motor system, along with the ability to 3D print a functional rail system, all of which needed to fit inside the dimensions of a slim-line sword body. Without being fragile, or heavy.
Simple, right?
As with many of my projects, I used high-quality rechargeable lithium-ion batteries to power the mechanism. A USB-C port is stealthily placed to allow for recharging the cell, and a two-way switch is used so that the user has full control of both extension and retraction. Overall, a pretty tidy build, and a really great project.
