I tried using a printed support arm initially, but the arm broke after a few days. I have been using this remix for 4 months now and its working well.
Following TaiwanWildEggs great instructions, I made a few alterations since I could not source the longer ties locally. I remixed the A2 cable clip slots to use two smaller 300 mm long, 4.5 mm wide, and 0.25 thick stainless ties. I started with three but found two to be sufficient.
Print the clips and support bracket for the swing arm using a high temp filament, in my case I used 3d Fuel's PCTG (a PETG alternative). It prints fine with the 0.20 structural setting and no supports.
Following the attached pictures, prepare 2 ties by removing the clips and cutting off the bent portion of one of the ties. Place the cut tie end inside the other tie and crimp the two together. The crimped end will be located at the printhead end on the cable and should be inserted into one of the clips using a pair of pliers. It is expected to be a tight forced fit, as it is used to hold the assembly in the support bracket attached to the swing arm once it’s installed on the cable.
The rectangular support bracket should be attached to the swing arm using two zip ties and I used the two original cable ties around the support bracket, cable, PFTE tube and swing arm.
