BambuLab Starter Kit that includes:

• Top Hole Cap
• Side Filament Guide
• Side Spool Holder
• Easily Removable Chute Bin

I checked most of the designs related to "Side Spool Holder" and "Chute Bin" for BambuLab P1S but couldn't find exactly what I was looking for. So based on what I have seen and what I needed, I created my own designs from scratch using the ideas of others. You can check models I am inspired from:

• bambu-lab-magnetic-chute-cover-poop-management-sys
• thing:6073397
• side-spool-holder-with-filament-guide-remix-of-bas
• bambu-lab-x1c-p1p-foldable-side-spool-mount

Note: I couldn't check if these fit on P1P or X1 as I only have P1S, so if you make it for those machines please let me know the result so I can update the description.
 

Filament:

• I suggest to use PETG or stronger.
  • You can use PLA, it works as well but others will be more stronger
