Description

3D Printers are getting faster, but longer hotends are harder to manage and the CHT doesn&apos;t scale much past a volcano meltzone. Here&apos;s a geometry that should scale, and testing indicates a flow improvement of 50% over the typical spacer. 

Made using a copper bolt, crappy drill press, and a jeweler&apos;s saw. You can make one too, so please share when you do a better job! And maybe help me come up with a clever name ;)

Names in the running (as commented): 
- Xylem Nozzle - Xylem is the plant tissue water and nutrients are pumped through
- XHT (Xternal Heating Technology)
- Xtruder
- &quot;X-Flow&#x201D; or the &#x201C;Cross Flow&#x201D;

Details

Most details are in the video, including how to make it. I'll add details here as I continue experimenting.

Components

1 × 1 M6x20 Copper bolt
1 × Jeweler's Saw and blades Use the biggest blade
1 × Drill Press
1 × 10-15 Degree CNC V Bit Aliexpress: (Do Degree10-0.1 for 10 Degree and 0.1mm tip) https://www.aliexpress.us/item/3256805260800615.html
1 × ~0.7mm PCB Drill Bit Size is approximate. Just make sure it fits your blade. Aliexpress: https://www.aliexpress.us/item/3256805429029496.html
