Adapter for exhaust fan on the X1C, usable with 100mm ventilation hose. 4 magnets keep it secure to the back while in use, while still remaining easy to remove if needed.
The magnet holes are for 10x3mm magnets, with glue, smaller should work as well.
Most any settings should work just fine, it's a very simple model. Suggested using minimum infill and maximum layer height to minimize print time.
