In the past I indeed had name customizations enabled for the lock. However, I had to remove this due to changes Shapeways made to the minimum allowed wall thickness. The lock is actually 1mm thick and the new min. allowed thickness is 1.5mm. Since a name customization in essence always means a new model, the lock will never pass Shapeways' model checker and never reaches production. I have actually tried the lock with a thickness of 1.5 mm, but that unfortunately didn't fit anymore comfortably through the hinge gap. Also, making the lock even thinner is therefore also not an option and I was lucky to have created the (non-customized) model when 1mm was still allowed!
