(I set it up began putting the bolts in so you see where the paint scratches and then used a round mini metal file to take a bit off)
The bracket is designed to fit over the original threaded rivets that hold the original hotend. Then using either the original bolts or any M3 (i used my own so can not confirm the originals are long enough) the front part of the bracket locks it in place. The fan legs are designed for M2 insterts to hold the original fan with M2 bolts. The original could thread themselves into the plastic but i have not tried.
The CRTouch spacer lowers the sensor to the correct height. Im am using the UHF version of the rapido which sits lower then the normal one. Attaches with M2 bolts (you will need longer ones then the original)
Last file is a tweaked version of the duel-5015 fan mod by Hoon. The original wasnt low enough and the lowered version kept hitting one of the stepped motors. Used the bracket from Hoon's model and lofted my own exhausts.
Print settings i used (I printed with Fiberlogy PCTG - Graphite).
The author marked this model as their own original creation.
