Mecha Handcuff for SmartDoll & DD3-DDdy is now available. There are 2 colors here: The Flat black version and the Crystal version. And there are SmartDoll version and DD3-DDdy version.
The two versions are made in different material. The Flat Black one is made by 3D FDM PLA printing, it is more rough (Please do not get one if you are looking for a perfect molding grade of plastic) and the Crystal one (slight clear blue with a bit yellow in color) is made by 3D SLA Resin printing (which is way more smoother than the FDM Flat black version, but still, if you are looking perfect molding grade of plastic, don't get one please.)
Also the Handcut is directional, meaning, you have to figure out the right direction to put them into the SmartDoll / DD3-DDdy arm.
