I wanted a soft cushion I could print myself. eSUN TPU 95A on a Creality K2 Pro

I wanted to make my dad a present: a support that lets him rest the body of his guitar on his knee. The plan was to print it in PETG. The problem is that PETG is hard, and pressing it straight against a guitar would leave marks, so I decided to put a soft cushion between the PETG and the guitar.

That means TPU. eSUN’s TPU 95A happened to be on sale on Amazon at the time, so I bought a spool to try it.

This was my first time printing TPU at all. On top of that, my printer is a Creality K2 Pro, and I had heard that TPU cannot be fed through its CFS (Creality Filament System), so it was also my first time feeding a spool directly.

With drying and a speed cap, it printed on the first try with no jams
The 95A hardness is just right for a cushion. It dents when pressed, but it is not floppy, and it is doing its job against the guitar
It works on a K2 Pro too, fed straight from a top-mounted spool holder

Taming filament moisture with a strong desiccant: my CFS went from 65% to 39%

Damp filament prints badly, so I bought a filament dryer and started drying spools before printing. Trouble is, my Creality K2 Pro feeds filament through a unit called the CFS (Creality Filament System).

So the spool gets dried, and then it sits in the CFS at the mercy of whatever the humidity in there happens to be. Which rather defeats the point — so I bought the KING “OZO” strong desiccant, ultra-fast type (OZO-Z10). Here is how that went.

Humidity inside the CFS dropped from 65% to 39%
It climbed when I opened the lid to swap filament, then fell again once it was closed
Only three days in, though. Whether it lasts is still to be seen
