Had to burn a few candles to make this thing in time for the current Printables contest - Upcycling of the new Prusament spools.

My idea is SpoolCore SFF – Mini-ITX case from Prusament spools - see actual photos below.
Would be interesting to hear what people would say on it.

Whole PC can be fit between 3 upcycled spool sides:

Question about storing and using filament

Phil — Sat, 02 May 2026 17:05:04 +0000

After drying a spool of filament (at the correct temperature and for the correct time per the manufacturer's guide). Then I put that filament in a dry box with desiccant till I need it. How long will that filament stay dry and ready to print in the dry box?
Does this dry box time vary by filament type?

INDX & Buddy 3D Camera

I'll be starting the build of my Core One soon while I wait for my INDX to ship. I see some advising in the build instructions to route a USB cable for the Buddy Cam making later addition of the camera easier.

Do any of you know if the Buddy Camera will be compatible with the INDX system?

MMU Boot Rattle

GregorPrinter — Sat, 02 May 2026 12:32:02 +0000

Hello everyone, I recently installed my Prusa MMU3 on a Core One printer and I’m experiencing an issue during startup.

Right after booting the printer, the MMU starts moving and produces a loud rattling noise for about one second. It sounds like the idler is trying to find its position. After that, the unit seems ready and no error messages are shown.

I did some research but couldn’t find any videos or examples where the MMU behaves like this. In other setups, the idler appears to move smoothly to its end positions without noticeable noise.

I already checked the following:

The idler drum rotates freely
The small gap to one side (as described in the assembly instructions) is present
The idler is firmly mounted on the shaft
on both the MMU and printer is up to date
No error messages are displayed

Despite all of this, the rattling noise during initialization remains.

Has anyone experienced similar behavior or has an idea what might be causing this?

THANK YOU SO MUCH
