A MUST upgrade for my Creality Ender 3

I ordered this tubing AND the fittings for my Creality Ender 3 Pro at the same time as I ordered the printer as it's one of the weak points. The Capricorn tubing and the fittings from Spool3D fit perfectly and made for a well running printer!

Just buy it!

I hadnt bought Capricorn tube for the longest be honest I just thought it was snake how much difference could it make... Then decided why not I'll check it out...well I can tell you yes, yes it does make a difference! The filament path is so smooth its not even funny! I'll be putting it on all my machines now!

this is to replace the stock filament tube on an Ender 3. Easier to insert and remove the filament, love it!

Easier filament changes.

Since changing out the stock ptfe tube for the Capricorn product I find changing filament easier as the tube end does not distort when printing at high temps.

Awesome tube!

Used this for my Bowden setup and print results were greatly improved! Recently put my printer inside an enclosure and I guess the heat made the filament stick to the old ptfe tube as as it made my extruder struggle. Really recommend this tube!

Decent product - excellent tolerance

Replaced the standard opaque bowden PTFE tubing with this and did the same prints then visually inspected for any differences. I didn't really expect any improvement and I wasn't disappointed. It prints exactly the same as the standard tubing. No better, no worse, no changes to any slicer settings required. On the other hand, I had some filament that had lumps in it and because of the tolerance of this tubing it blocked the filament at the extruder. Saved me time from having to dismantle the hot end to remove a jam like in the past. I LIKE this part of it and the tolerance is why I bought it in the first place.

Good stuff!

I use this to replace the cheap aliexpress ptfe tube in my bowden setup and and the difference is night and day. This tubing is very low friction and performs spectacularly

Very Good Product

I like how it comes as one long tube that I can cut myself to the size I need it. It's running on very high temps now and by the looks of it, handles them very nicely
