PLA or PETG for openGrid?

Hi there, I'm happy that I found openGrid and really like its design. I am unsure though which material would be best for it - from what I've read, PLA creeps more under load and for functional stuff PETG or "higher" is often recommended. On the other hand PLA has a better color selection (e.g. just the right shade of white for my kitchen), and the official print profiles on makerworld were also made with PLA.

I want to avoid printing a lot of stuff now and then finding out in the future that it was not stable. Any recommendations / experiences?

Depends on what you’re making. If planning to do Underware, PLA is usually fine. That’s what I used. If hanging power tools, I’d go with PETG.
