Note: This is not compatible with The Claw fang duct (https://www.thingiverse.com/thing:5202213). You will want to use the extended adapter at https://www.thingiverse.com/thing:5250192. A low profile adapter (5mm tall) for the BIQU H2 that lets you replace the 35mm heatsink fan with a 40mm one (4010 or 4020). This adapter is only really needed if you want to run a quieter fan or need more cooling if running very high nozzle temperatures, otherwise you should stick with the 35mm fan. Depending on your setup and which fan you go with, you may lose some x travel to the left. Be sure to make adjustments to maximum x travel and your probe offset in your printer's config.
