Crazy PETG stringing on mini
I recently got my Mini around a few weeks ago and have been mostly printing in PLA with some very very slight stringing but, once I tried PETg, the stringing is now quite crazy with Pruusament PETg and the default slicer profile. I suspect it's the humidity because where I live, humidity is around 80% year round. Would it make sense to get something like a filament dryer/container?

Here is another angle. Any help would be appreciated, thanks!

Yes, drying should help tremendously. I made one of these:

They added 3D printed spool chambers to a cheap dehydrator. They have two stl files, one for large printers that won't fit on the mini, and one that is 1/6 of the part. I made one that is 1/3 of the part and just fits on the mini if you rotate it. It is more stable. The clips don't work well. I taped the pieces together with silver HVAC tape.

You can get the files from my site:

At the bottom, get the v2segment73mmx2.stl to print, or v2segment73mmx2.scad if you want to make more changes in OpenSCAD.

Hi, thanks so much for the tip, just curious, what is your opinion on the esun filament storage box and dryer?
Thanks!
RE: Crazy PETG stringing on mini
I haven't looked at it. It does look like a good idea, especially if it is 80% humidity where you are. I pretty much am drying two spools at a time though and they stay dry for a day or so after being in the dryer for a few hours. So, I am not drying while printing. It might be worse where you are, but I suggest you have the ability to dry two at a time, the one you are using and the one to use next. Otherwise you will be waiting half a day or more for the next spool to dry.

Thanks for this! I just ordered the dehydrator and will build one this weekend. What material did you print the walls out of?

I used ASA, but it requires a full height skirt and an enclosure to keep it from warping and pulling off the bed. I think you could use PETG.

Tried printing this with PETG but noticed there was an issue with your .stl file. Do you see the same thing in prusa slicer?
