Ultra-compact ultra-light hotend for Anycubic Kossel

thingiverse

Edit 2020/01/20: I just came across Thomas Sanladerer's video review of a hotend very similar to the one I put together, so it seems I'm on the right track. :)\nThe one in his video looks like it has significantly different dimensions, but the same basic design is used. It comes from a company called Deltaprintr. I prefer my creation better as it uses standard threads for the nozzle and offers various nozzles available.\r\n\r\n-------------------\r\n\r\n**TL;DR:** This knocked 51g off the effector. Using TMC2130 drivers ([plus my other modifications](https://www.thingiverse.com/glabifrons/collections/glabifronss-anycubic-kossel-mods)) with this hotend and Klipper firmware, I was able to print 400mm/s with fairly nice results (very minimal ringing) at a speed of 51g off the effector. The limit turned out to be the TMC2130 drivers as I ran into problems when I raised the current past 0.9A. I've since switched to TMC2208 drivers so I can raise the current further, but I've not yet run any more speed runs.\r\n\r\n-------------------\r\n\r\nI wanted to try a combination of parts from my Anycubic Kossel Linear Plus that no one else has put together, so I made my own mount for it. This uses the following parts:\r\n1. Heatsink & heatbreak from Trianglelab.\r\nIt doesn't have a name 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.\r\nhttps://www.aliexpress.com/item/4000083295807.html\r\n2. Heatblock, heater, & nozzle from Trianglelab.\r\nThis also needs a name as 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.\r\nhttps://www.aliexpress.com/item/32697889176.html\r\n**Update: 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).\r\nhttps://www.aliexpress.com/item/32828646261.html**\r\n3. 3010 fan driven at 80% to reduce noise.\r\n4. 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.\r\n\r\nNote that this combination does lower the nozzle by a few millimeters intentionally as spacers are provided for moving your favorite part cooler duct down by 2.5mm or 3mm.
