tronxy auto leveling sensor fine adjuster mount and extruder fan holder

thingiverse

I redesigned an extruder fan mount combining great ideas from two existing designs. The default fit of one design was loose and impossible to adjust, so I printed it but couldn't get it to work well. I preferred not to go back to the standard extruder fan mount, which I had been using with a separate extruder fan mount where I can lift the fan in and out if I have filament issues. I set up a mock-up using the original parts of both designs but it failed on the adjuster part because it was too thin and fragile. It didn't have enough tolerance for a machine that isn't producing perfect prints, so I redesigned the adjust from scratch. The new design uses straight block edges with a reasonable mm gap for the sliding part. It uses a bed level screw M3 and a left over nut from the original kit, as well as any spring from a ball point pen. The thumbscrew was too fat, so I used one from a different thing which is thinner and prints nicely. Someone else's ideas were combined with a few tweaks and mods, plus a redesign of all parts. They are printable as separate STL files or the whole lot on one STL. It's advisable to only print the main body with supports if needed but you can just about get away with zero support. Print items as they land on your slider for best performance. The sliding block part has a large hole at the bottom that should consume the screw head. You may need to drill out slightly depending on how accurate your printer is. The slots at the rear are for the nuts to sit in. I'm happy to receive feedback.
