Ultra-compact ultra-light hotend for Anycubic Kossel

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 (https://www.thingiverse.com/glabifrons/collections/glabifronss-anycubic-kossel-mods)) 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.

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.

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.
