Snapmaker U1 Filament Feeder Covers

These covers are direct replacements for the factory covers.  They incorporate tube couplers in the design.  You need only to insert the collets.

Print these face-down, applying supports for the attachment arms and for the little tab on the release.  The model is designed with integrated supports for the release button, as separate bodies.  When printing, use a non-compatible material for these.  I used PETG for the body and PLA for the support arms.  Once complete, gently flex the release button to begin breaking them loose and then press the support bodies out of the slots with a small screwdriver (or similar).  They will pop right out.  See the included screenshots from Orca to see what I mean.

Numbers and logo are separate bodies and can be printed in a different color, if desired.

To assemble, remove the factory cover by extracting the two screws from the back.  Transfer the 2 metal gromets which guide the filament into the feeder motor from the factory cover to this one (flat side "up").  Gently flex the plastic arms backward to remove the two, clear LED diffusers from the factory unit (be careful not to launch them across the room!).  Install them in this cover by placing the front into the hole (they will be at a downward angle) and then press firmly against the back to snap it into place.  You can use the back of a small screwdriver or pen, if needed, to get them snapped into position.  Replace the motor unit and reinstall the screws until snug (don't overtighten them).

Install collets by squeezing the fingers together and then gently pressing them into the holes.  They will snap into place.  When inserting tubing, be sure it is fully seated inside the feeder cover.
