Bora Duct Fan Mount for Ender 3/5 by sychan

Last crawled date: 3 years, 1 month ago

This is a modification of LeoN's Bora Duct - the original design is great but I made some small alterations:
1) Put holes all the way through layer 1 of the base plate. I prefer not to put in extra trimming time on my prints.
2) Modified the 5015 fan mount to take M4 screws diirectly, instead of needing to be drilled out for M3 screws. On my printer the holes are large enough so that (carefully) threading in the M4 bolts works well.
3) Beefed up the cross section of the 5015 screw mounts to resist splitting on layer boundaries as the screw is threaded in. I suggest print with 4 walls and prethreading the screw mounts with a screw before actually mounting the fan
4) Trimmed off a section on the lower left of the base plate that covers where the X axis belt hooks into the carriage plate. This change has no effect on Ender 3's, while making the plate usable on the Ender 5.
You will need the 3 additional ducts from LeoN's original thing, this is just the modified base plate.
My print settings are similar to
