Printed on:
Ender 3 Pro
Result:
Works Ok, but incredibly noisy due to fan vibration. Modified the fan housing to take a power jack. Bought an external power block that had variable voltage built in
Feedback:
The upper shroud won't print the way the documentation says - had to print as per lower shroud. Support detritus is impossible to shift. Might be better to print shroud as an inner and outer? Notwithstanding these minot criticisms, many thanks for publishing the design
