Tevo dual Z upgrade

thingiverse

I have uploaded a couple of pictures of the finished duals. Only difference is I used 3mm carbon fiber for the screw brackets. Note: It was mentioned that there are a few holes missing, Sorry about that, Since I didn't print them I didn't notice. Easy fix for you guys though. :) I have had it running for a couple of months now and it just runs constantly with minimal adjustment between prints. This is a huge Improvement over the single screw. Accuracy, Repeatability and speed, I run my DIT printer over 150mm/s with good results. These are brackets for the Tevo Tarantula dual Z upgrade.
