I printed a Key Fob case in PLA, and it broke, so I am thinking on using a stronger material. Looks like CPE is the right choice, but I read that since it prints hotter, it may melt the PTFE coupler.
Do Ultimaker 2 and Ultimaker 2+ use the same coupler?
So, ... How much does CPE printing really affects the coupler?
and... Where can I buy it in the US?
Thanks
Alejandro
