ENDER 5 PRO cooling duct SATSANA remix

thingiverse

This is a remix of the SATSANA Fan duct https://www.thingiverse.com/thing:4369859 This design seems to be very good and uses stock fans and bolts. Unfortunatelly, on the ENDER 5 PRO, a belt ending prevents the SATSANA E3 to sit properly. The alternative solution for E5PRO is the https://www.thingiverse.com/thing:4593935 BUT the solution to avoid the interference has been to extend the whole duct, as a consequence, the two scopes are not centered around the nozzle. I assume this may lead to cooling not perfectly distributed over the filament I propose to introduce a cavity to allow the end of the belt to fit and keep the Eric Anastas design. Moreover, after having performed the curling test defined here, https://www.thingiverse.com/thing:3852651 i still wanted to get the original concept improved, so I lowered the two scopes by 2 mm I gives me similar results of the https://www.thingiverse.com/thing:4112253 slighlty modified (lowered the scope + make the design supportless) but with Satsana like designs the nozzle is more visible and I assume the cooling to be efficient in more situation than 4112253. Moreover, 4112253 shows very low clearance with hot end and i faced some warping of the scope even in PETG. I didn't want to keep such contact so i decided to move to satsana like design. Hope this will help https://www.thingiverse.com/thing:4369859 : not applicable to my ENDER 5 PRO https://www.thingiverse.com/thing:4593935 : applicable but scopes to big versus original concept + rough surfaces https://www.thingiverse.com/thing:4112253 : very good design, good curling tests results but warping after one print due to low clearance with my stock hot end https://www.thingiverse.com/thing:4112253 + personnal MODS : scope lowered by 1.5 mm, shape simplified to avoid supports, very good results at curling test but still some evidence of hot contact after one print https://www.thingiverse.com/thing:4369859 + personnal mods : spot face to allow 55PRO belt compatibility + scope lowered by 2 mm => the design proposed here
