I printed the cable chain by papinist and soon found out that the chain can come above the bed when your bed is moving in far top the inside. You can damage your nozzle when it moves over the chain in that position. To keep the chain below the bed I created a little arm based on the bed spring protectors from AndrewUsov.
I printed in PLA - 190 nozzle - 40 bed - 80% - 0.2mm.
