Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4088582.

Edit 2021/06/28: Please see part 2, the heater block section. There is finally a new one available. :)

Edit 2020/01/20: I just came across Thomas Sanladerer's video review of a hotend very similar to the one I cobbled together for this, so I guess I'm on the right track. :) The one in his video looks like it has significantly different dimensions, but the same basic design. It's from a company called Deltaprintr. I like what I put together better as it uses standard threads for the nozzle, and has a variety of nozzles available.


TL;DR: This knocked 51g off the effector. I was able to print 400mm/s with fairly nice results (very minimal ringing) using TMC2130 drivers (plus my other modifications) with this hotend using Klipper firmware. The limit turned out to be the TMC2130 drivers, as I ran into problems when I raised the current past 0.9A (the chip has a design-limit of 0.96A). I've since switched to TMC2208 drivers so I can raise the current further, but I've not yet run any more speed runs. I may upload a video later.


I wanted to try a combination of parts I had in my Anycubic Kossel Linear Plus, but it doesn't look like anyone else has put this combination together, so I made my own mount for it.

This uses the following parts:

  1. Heatsink & heatbreak from Trianglelab. It doesn't have a name, sadly, as I'd like to be able to refer to it by name. It's the external dimensions of the heatsink used in the Ender 3, but with fewer/thicker fins and a heatbreak closer to that of a MicroSwiss. https://www.aliexpress.com/item/4000083295807.html
  2. Heatblock, heater, & nozzle from Trianglelab. This also needs a name. It's miniscule and not much more than a piece of threaded aluminum tube with a cylindrical heater wrapped around it. If it's currently listed as "unavailable", check back. I asked them about this and they said they were improving the design and would be bringing it back soon. https://www.aliexpress.com/item/32697889176.html Thanks to RockerX4 for the comment pointing me to another source for what appears to be the exact same hotend (even uses the same pictures). https://www.aliexpress.com/item/32828646261.html Update: I've been going back and forth with Trianglelab since they pulled the original heater block I used and they seem extremely confused (being very kind here). After changing their answer numerous times, they said they will not be making a replacement. Today I found this (which looks like an updated version of the same thing): https://www.aliexpress.com/item/1005002781227348.html One big difference is the new one is listed as "copper" (although it's obviously brass) so will be a bit heavier than the older aluminum version. If anyone has a lathe, it should be ultra-simple to make the block out of aluminum.
  3. 3010 fan driven at 80% to reduce noise.
  4. Various hardware, including 2x M3 nuts (pressed in the part cooler side), some longer M2.5 screws to mount the fan duct, and the rest (I think) were stock. I may have used screws 1-2mm shorter for the part cooler blower, but I'm not sure (I've been running this for a couple weeks now, haven't had to modify anything).

Note that this combination does lower the nozzle by a few millimeters, this is intentional (see below). Spacers are provided for moving your favorite part cooler duct down by 2.5mm or 3mm.
