AMS Friendly Spool Ends for Prusament Filament

The Prusament spools do tend to work with the Bambu Labs AMS, but they are technically wider than Bambu's stated maximum width, and there are a couple of other things that occasionally cause issues.

Not only are Prusa spools a tad too wide, they also have two cut outs on either side which make those sections particularly thin and can occasionally catch on the filament guides in the AMS.

These spool walls are designed to perfectly fit inside the cardboard tubes that Prusament spools are provided with, working perfectly with their refill spools, and if you're feeling confident with removing the walls from Prusament non-refills, will fit them too.

Features

• 3mm thinner overall spool thickness, meaning they are within the Bambu Labs recommended size
• Features built in filament clips of a similar design to those on the Prusa ones, but is actually more effective
• Available with a few different designs

UPDATE

23.11.23 - I've added angled holes to just above where the cardboard tube sits so if you use these for respooling, you can clip the starting end of your filament into it.

Different versions available

• Plane/Generic
  • The same as all the others, but just no label built in
• Quick
  • This features no label, and none of the “styling” holes, allowing for a quicker print (this still features the built in filament clips)
• PLA
  • PLA Single Colour
    • Features a PLA label ‘engraved’ into the sides by 0.55mm allowing it to be visible whilst printed in one colour
  • PLA Dual Colour
    • Features a PLA label ‘engraved’ into the sides by 0.05mm. If printed in one colour this will not be visible, but it allows quick and easy fill painting. If painted with a different colour, this will be printed on the base layer with the rest of the print (as in the photos)
• PETG
  • PETG Single Colour
    • Features a PETG label ‘engraved’ into the sides by 0.55mm allowing it to be visible whilst printed in one colour
  • PETG Dual Colour
    • Features a PETG label ‘engraved’ into the sides by 0.05mm. If printed in one colour this will not be visible, but it allows quick and easy fill painting. If painted with a different colour, this will be printed on the base layer with the rest of the print (as in the photos)

Notes

• PLA should be fine for most uses, the only reason you'd definitely want to print in PETG or something else is if you're using it with a reel of any material other than PLA and you'll be putting it in a heated filament dehydrator. In that case you'll want to make sure it's printed in a material who's deformation temperature is higher than the drying temperature of the filament you're using on it.
