Great model - Have printed this but chose to use PETG as it's a little more flexible.
I'll also design a clip to hold the spanners in place as some of my spanners are a bit loose (yes I'm probably using the holder a little differently as I have a few wrenches and also some spanners/wrenches of the same type) - will post it when available :-)
I've been using it a couple months now with no major issues. The tightness between a couple is still there but i'll adjust that once it eventually breaks 😅
Im keen to know how PETG lasts as im doing a lot more with that now rather than PLA
