Drag Chain

This Drag Chain model is not entirely created by me, I have had it for some time but I can't remember where I got it from. I think I made enough changes to call it original but if someone recognizes the original model can share the link with me and I will edit the post as a remix.
I created this drag chain model because I got tired of creating models that last a few weeks and then start sagging. This model has longer attaching pins and also has an additional side support with screws.(4x1.5mm)
Another option I needed is for the drag chain to only provide vertical support but allow bending in both directions.
I also attached it in .stp format so you can create your own clamping solutions, in the uploaded files I attached the models that I use specifically for my needs. If you want to cool the model I suggest you print it at layer of 0.2 with at least 4 top and bottom layers and 3 walls, infill is enough 10%.
If the model shows interest I will create more attachment solutions but until then you will need to create your own anchoring solutions.
