Small print in place UK style construction road barriers.
There is two versions one with a support on the pin to join the barriers together that just needs to be cut off and one without the support but a support will have to be added manually when slicing.
The barrier are roughly 40mm tall and 80mm length
If you own an AMS unit I suggest you check out V2 of the barriers - https://makerworld.com/en/models/490711
