Cheap and fast enclosure Prusa XL

I find the all the attempts on this site for full enclosures really nice looking and high build quality. However, I just want to get something temporary (hah!) until Prusa get into gear and sell their own enclosure. Quite honestly I think Prusa painted themselves in a corner with the XL design. It is focused on the mechanics and dynamics of printing and did not consider an enclosure at all.

I put the parts and the build guide here: draft and dust guard

It takes about an hour to put together and 20 euros in parts. It does not look pretty, but it does work well. The only issue I have is that the clips are a bit weak, I might beef them up a bit.

Any ways, do you guys have any comments? Do I need to add different tube sizes? What diameter is easiest to source for you?

RE:

Thanks for sharing. How hot it get when the Heatbed is at 110c° in a 18c° room? My quick build removable enclosure goes to 48c°.

I think one downside to your design might be that all electronics get heated up too.

Just because you made me curious, I put a temperature sensor in the enclosure and waited 2 hours to see how cold it is:

I turned the bed on to 60 C and waited 30 minutes:

It was still rising but I had no need to run the printer at the moment. I have a 10 hour print planned this week, so I will report back when that is done.

I normally print PETG/PLA with a bed temperature of 60 C at the start and 40 C after 20 layers or so (M140 S40 command). So I am not terribly interested in 110 C use case.

Regarding the electronics, the nextruder should be able to handle the hot air above the bed any way right? I was thinking to check in the summer to make some air vents in the back of the tent so the power supplies get fresh air. Those are probably not made for this.

The Nextruders on the XL will not feed filaments over 42C-46C. I have been printing high temp Filaments for the past few months and have tried everything. Any test print over 42-46C the filament will stop feeding. This Nextruder needs some sort of forced air cooling to keep the gearing cool.

Well good news, after running several hours with print bed at 60 C in a 16 C room, the temperature in the enclosure tent got stuck at 26 C. This is perfect for my taste. It reduces warping and power consumption but nothing excessive.

Only caveat is that I used only 6 out of the 16 bed elements.
