A decent fitting fan mount but the screw holes could be better positioned. And It could stand to be longer. I will start from scratch when fixing it.
On the Dual print head assembly, It only fits from the front. And you must angle them towards the middle for 2 of them to fit.
The next version will fit one fan to both Print head cooling fins. I believe a single 40mm fan provides sufficient airflow for 2 J-heads.
