Hello,
O am planning to build a wall mounted glue up rack along the lines of this one:
The idea is to fix metal rails on the wall and 3d print a sliding attachment for the clamps (one for each clamp so that I can basically adapt the clamping width to the piece).
Thanks in advance !
What do you suggest to use PLA or PETG or eventually PETG-CF?
Check whether you can get a Scheppach Plano. They work pretty well. 
Thanks for the tip I already have Bessey clamps mounted on tubing so it would probably be chaeper to build a rails system with a a 3D printed trolley 
Ordinary PLA is more rigid than any of the modified PLA , PETG, ASA, ABS filaments and prints easily.
If you have extreme temps and must have a high temp filament then the recommended filament is PET-CF (Which is NOT PETG-CF !).
My un-conditioned garage sees 110F / 43C temperatures in mid summer and I have not yet had an issue with PLA parts.
On the other hand, my insulated garage in Arizona, I’ve seen failures long term hanging items with PLA fixtures over a year (slow bending, followed by failure). If you’re just temporarily hanging projects for clamping PLA is fine.
What range of temps does your space get to?
My smaller LR4 has been seeing both hot and cold cycles since the beta and no issues yet.
That is called creep, the kryponite of PLA. PETG is too flexible.
I agree, PET is probably the easiest to print - creep and heat resistance you are going to get. I have had a lot of success with PC blends, but they aren’t beginner friendly and you need an enclosed printer.
That being said, is 3d printing the answer? If you are going hang something like that, you could use unistrut and get some bearing based trollies that ride along the inside with some eye bolts to hand whatever.
Maybe up to 90 something F? My MPCNC is fine in PLA out there. The loads of hanging tools, clamps etc. on the wall are just different I think.
Did you complete this project?
Hello,
I am still working on it. From a filament perspective I decided to do with ABS as my P2S supports it even if I am still struggling with corners warping.
What pipe diameter are you using?
3/4 pipes as I already have some that I use with the clamps fitting the same size
