Currently still in testing, any feedback is appreciated.

NOTICE: REMIXES ARE ALLOWED

The step file has been provided, feel free to modify it to your liking.

Notable improvements compared to default:

Cheap and easily replaceable wiper
It covers the hinge of the chute flap, lowers chance of any filament getting stuck or hooking on the hinge

Purge chute cover with a PTFE wiper for the P1S, P1P, and X1C series. Requires a M3 insert and a 6mm M3 screw to hold the PTFE wiper in place. This allows for easy changing of the wiper without needing to reprint the entire part like with glue in designs. Ideally you should print this using a filament with high temperature resistance, ABS works fine but if you have other materials like PA/PC or CF variants feel free to use those.

Please note that it is possible the model may appear loose if your filament has shrinkage after cooling, you may want to scale this model up or if you use Orca slicer you can adjust shrinkage % in the filament settings to ensure it is the correct size after cooling.

Orca Slicer, Shrinkage can be found when editing the filament

Assembly Info

Cut a length of ~15-20mm PTFE tube and make a cut to split it.
Use a screwdriver to help pry apart the PTFE tube.

3. Use pliers to help flatten out the PTFE tube.

4. Use a exacto or drill to make a hole

5. Install a M3 heat set insert into the part

6. Install the flattened PTFE tube, ensure that it is level with the top of the cover, if it is too tall you can trim it down. You can also use an Exacto knife to make additional cuts into the PTFE tube to make it more like a brush.

7. Install onto printer

Additional Notes:

If you do have silicone sheets or pads available, feel free to replace the PTFE with silicone wiper instead.

@edzieba

A nice concept, but the filament ooze during the post-first-layer-scan dwell time builds up in the area between the PTFE wiper and the stock wiper as the nozzle rests above that area.

The designer has replied

@Stephanos

That is a good point, I did place a chamfer behind the PTFE tube so that any filament oozing there can get guided down the slope but its possible some can get caught on the staircasing. I'm currently testing some other alternative solutions to lower the bulk of the holding arm.

@Stephanos

Hi, I have made a new revision. This should help address the issue you mentioned about ooze during the dwell time. https://makerworld.com/en/models/186746#profileId-205631 Feel free to test it out, feedback is always appreciated.

i may give this a try as well. the other one i printed from another user is next to useless.

@EngineeringProj

You remixed mine! I don't allow remix! https://makerworld.com/en/models/145761#profileId-158636

Please stop embarrassing yourself and go learn the difference between a patent and a copyright

Replying to @Stephanos :

I think your design is better than someone else's. I used TPU to print someone's model, but the result was very bad. The high temperature of the nozzle can cause waste and TPU to stick together, and it can damage the TPU print. So I only used it twice and threw it away, wasting my material in vain. Your wiping tool is relatively smooth and resistant to high temperatures, so the effect will be better. By the way, it's shameless to display model links through comments

@Nemshire

doesn't look like a remix to me. looks to me like it was modeled from scratch.

Printed well. About to test it on the X1C. Will keep posted on how it goes.

The designer has replied

@Stephanos

That's good to hear! Another user has noted there is possibility of ooze getting picked up between the new and original wiper during post first layer scan (only affecting X1C). I have made a revised version that should help fix this, let me know if you have any problems or if you need help. https://makerworld.com/en/models/186746#profileId-205631 Happy printing!
