Robert217@jeremy_bagley Yes, this comes with a locking pin, you can see it in the image as the white circle inside the KTB. The separate locking pin works better with a small padlock, while the included locking pin works better with a plastic tag or wire seal. However the already supplied pin can be easily drilled out to accommodate a padlock also.
And yes the products are made to order by Shapeways.

Robert217Great, I have posted a new version this morning, it has an inside diameter of 26mm compared to the regular diameter of 22mm. If there is enough interest, I will post one that has a smaller diameter as well.
