Drag chain mod for Twotrees TTS55 or TT55S

I printed in PLA, any material is ok.

Please note than I had to print a new board support in order to move usb cable on the right allowing to put the board on the left. This is needed to shorten the path as much as possible otherwise new motor cables or cables extension is required.

You will need the following :

• 2 M3 x 8 mm screw flat head only
• 12 M3 x 8 mm screw whatever head
• 4 M2 x 10 mm screw whatever head
• 12 M3 4mm threaded insert nuts
• 2 M2 4mm threaded insert nuts
• 2 limit switches
• And a drag chain…

Document attached, don't hesitate to comment if you find errors.

In order for the limit switches to work with TT55S, you will have to flash the board. 

For TTS55, it will work as is.
