Description

Version 2 of my purge chute cover with a wiper

https://makerworld.com/en/models/180812#profileId-198976

STEP files have also been provided for your remixing convenience :)

This newer version eliminates the arm sticking outwards and the entire flap is made of PTFE tubing. This means nothing should stick to it, and it can move out of the way if the nozzle moves into it. The protrusions have also been extended to provide a much tighter fit to avoid it ever getting knocked out by the print head.

Reminder

Before proceeding with assembly, after the part has been printed, check that it fits snuggly inside the purge chute and isn't loose. You may need to wiggle it slightly to get it to slide into place. The fitment is provided by protruding corners to allow for easier sanding if you need to slightly adjust instead of needing to print the entire part again.

Adjust for shrinkage/thermal expansion accordingly to the material that you are printing with.

Materials

If you print primarily in PLA, there shouldn't be much issue printing this in PETG as the PLA does not stick to PETG. I do not expect anyone to go and buy an entire roll of PA/PC or CF filaments just to print a tiny part, feel free to use what you have, but minimum I would recommend is PETG.

This material guide may help you decide:

Be aware ABS/ASA and some other higher temp filaments release odors and VoCs while printing, be sure to work in a ventilated area.

Assembly

This design replaces the M3 insert with a M3 hex nut due to the location of where its installed.

PTFE wiper prep and installation is same as before except the tube length is 25-30mm.

Cut a slit and flatten the PTFE tube with pliers

Secure the PTFE tube to the printed part with a M3x6mm screw. A M3 washer can also be used here

M3 socket/cap screws with a head smaller than 5.5mm should be able to fit all the way through

Any and all feedback is appreciated, happy printing!

It's very similar to this one : https://makerworld.com/en/models/145761#profileId-158663 . Did you remix that?

The designer has replied

@Stephanos

It was designed from scratch to make use of what you may have laying around instead of having to cut up some silicone mold. The creator of that model seemed pretty butthurt about people making their own designs. They told people to make their own if they don't like it then says remixes are not allowed when you do make your own. As far as I'm aware, they do not own a patent to the design to warrant the sort of arrogance they have.

Replying to @Stephanos :

Yes do their own and yours has the same corners, so you remix that and it's not even an your original idea!

@Stephanos

Replying to @3dprint4Life :

I can assure you it is not a remix, I have provided the source STEP file for remixing and already shown the design process in the V1 version, I am remixing my own V1 of the design. I am the original author of it from beginning to end without referencing any other designs aside from borrowing its concept. https://makerworld.com/en/models/180812#profileId-198976 The design is not mine and its not EPs either. Another design was uploaded 2 weeks before theirs, except they also provided a STEP file for remixing, so as far as I know the one in the screenshot you sent is actually remixing another model then sharing without attribution and prohibiting remixes on top of that. https://www.printables.com/model/709309-bambu-lab-x1-poop-chute-system/files

this wiper worked out much nicer than another I tried, great design and concept, thanks

@edzieba

Printed in PETG, works nicely to 'catch' purge bundles under the lower lip of the PTFE strip, reducing the change of them popping out of the chute during wipe motion.
