The LearnMakeCupcake bot kept blowing PTFE barriers so I gave them that clamp setup. It’s just a 1/2″ copper pipe coupler (the kind without the stop.) I bought a few of them and cut a slot the length of it with a dremel cutoff wheel. It’s a perfect fit around the PTFE barrier. I can’t remember who first proposed the idea, but it was someone on the Makerbot list.

I was posting the upgrade as a fix and have been using it for quite for a quite while. thought the original idea came from someone’s blog. it was from someone early on.

I built this mod this weekend after reading an idea on the Google groups. Got all the parts from Home Depot – how funny! Will this fix truly enable me to say “You have failed me for the last time Makerbot”?
