Will need to design an updated filament sensor support with less flex as a strong enough extruder can yank the dry box out (!) -> DONE, replaced problem file and updated picture. (edited)
It's a nice mod, i really wanted to have it because the NAV 5015 mod is not enough to cool a 1.0 nozzle decently, unfortunatelly the duct doesnt fit with my super pinda mod and the 4020 hotend fan mod. Had to print it to make sure so at least i can say it prints nice. (Oh and btw its hard to find a 5020 fan for a decent price as they are kinda rare) (edited)
