10" Pegasus Build

[BLKKROW]

So the Z coupler tubing on one side has gone bad.



I have a couple of these couplers being shipped my way. http://www.ebay.com/itm/331160051416

I've seen mixed reviews on them, but I figured its worth a shot to test them. Does anyone know what diameter tubing I would need if I want to go back to that? 3/16 inch?

I have the 12" Pegasus and found the Couplers that you purchased run into the X Carriage. I cannot get the Z axis low enough to get the nozzle in a good position for the bed.
