XOL2 Toolhead by Armchair Engineering Kit

From the repo:

Originally a project to slap 5020 blower fans onto Mantis, this toolhead variant started as an attempt to improve parts cooling, spurred on by Derpimus' noted cooling woes on his DOOMCube. After finding that the 5020s were just plain too fat to fit without looking like a standard Ender 3 Thingiverse special, I abandoned the large fan dream in favor of better cooling efficiency and lighter weight. This new and improved dream was also corrupted by my then budding and now all-consuming love for worm gears.

Features:

• Better airflow than Stealthburner (6-7 CFM through short ducts vs 4.6-5.2 CFM through long ducts)
• Improved resonance management compared to Mantis 5015
• Support for Sherpa Mini-pattern extruder mounting as well as Annex Engineering's Double Folded Ascender worm gear extruder
• Support for JosAr's Klicky, VinnyCordeiro and WhoppingPochard's PCB Klicky, and Nionio6915's Euclid

Kit includes:
