Bambu P1S Purge Chute Extension

I've had my Bambu P1S for about 3 months and in that time my printer has clocked up more than 1500 hours, most of it multi-colour printing.

In that time I've had so many issues with the chute backing up spilling onto the build plate, or knocking off the printer head cover and its been driving me nuts. I've tried just about every nozzle wiper there is without success, even those with silicon or pieces of the A1 silicon wiper.

On looking at the chute more closely, it seemed as though the issue was that when the printer was purging, some of the purge was somehow looping over the trap door hinge inside the chute, or over the lip of the chute, it then got hooked there allowing subsequent purges to build up, causing the clog. So I bought some high temperature PTFE tape from Amazon and carefully stuck it around the edge of the chute, but that still left the trap door. 

Then I found the design by z3d on Printables, and this worked ok, but the purges, looked a bit strung out. I realised the original door extension was stopping the trap door closing properly as it was pressing on the lever at the back of the printer, so the purges weren't spooling properly. So I took z3d's design and modified it with a slot, slightly off centre as is the lever at the back of the chute. This allowed the trap door to close properly as the lever can push the trap door closed as it should, and for me, it seems to have stopped the issues. So I thought I'd share it as z3d did. I also made it a bit stronger, although there's not much pressure on the extension itself.

This works on my P1S, so should also work on the X1C. To install the part hold it with the flat part of the flap facing forwards and place the part on top of the hinge for the chute trap door. Just press down on one end and then the other and the flap should just snap onto the hinge. You might need to move it a little on the hinge to get it to be upright. 

Don't print this in PLA, only in PETG or some other heat resistant material, as apart from anything else, PLA tends to stick to PLA and this would defeat the object of the flap. I've been using PETG without issue.

If you're having the same issue as me, give this a go and I hope it works for you.

Good luck

Changed the orientation of the print after some people reported the flap breaking. This change should prevent this, but let me know any further issues please.
