Update 28/09/23:
- the main profile was split into two profiles to distinguish them easier and to reduce the time displayed on the profile (since the total time from all plates in the profile are added up): new profile names are 100% scale, … and 100% with holes, …
- some users reported that the original version is too loose and the adapter spins without the spool, thank you for the feedback! I have tested 98%, 99% and 99.5% scaled versions of the adapter and the 98% and 99% are impossible to fit (at least on my eSUN PLA+ cardboard spools). The 99.5% scaled version fits very, very tightly and is almost impossible to remove afterwards but it still fits. If you have troubles with the original (100%) scaled version in the AMS try the new profiles for scaled down versions (99.75% scale and 99.5% scale), I hope those fit better for you :)
Original description:
Simple AMS adapter for eSUN cardboard spools (20 cm diameter). Prints in 5 min with the supplied 0.28mm profile (10 min with prepare time) . Mounts to spool snuggly as friction fit. Can probably be used for any other 20 cm diameter spool aswell. Modeled to be most efficiently printed with 0.28mm layer height profile.
Most of the recent eSUN PLA+ filaments come with cardboard spools. Due to potential jamming, BambuLab does not recommend using such spools in the AMS. I am runing almost exclusively eSUN PLA+ cardboard spools in the AMS and had no trouble so far. However, if you encounter problems here is the quick fix.
A few considerations:
- If you are concerned that the adapter may rotate without the spool when/if it looses friction, I made a second version with three equidistant holes through which you can attach the adapter to the cardboard either with M3x4 screws or by pushing a bit of cardboard through the hole from the inside of the spool. If you are using screws make sure to use short (max. M3x4), flat and countersunk screws since otherwise the AMS may not be able to turn the spool due to collision with the dividers.
- Since the eSUN spools are quite large, the adapter needs to be quite thin to prevent the spool from getting stuck at the top cover of the AMS (1.2 mm rim thickness was already too much). This is why the adapter may seem quite flimsy but it is more than rigid enough for normal use.
- The adapter does not fully cover the filament storage holes and there is enough space to secure the filament as usual
