Printed in PLA and red TPU.... very simple design.


Quick print that has already saved quite a bit of the hassle of connecting back the AMS every time I use an external spool
This worked well for several spools of basic PLA but I started printing with glow in the dark bambu matter filament and the friction with the inside of this splitter was causing the AMS to think that the filament was stuck (I got errors loading and unloading the filament). I watched the filament move and as soon as it hit the split the AMS motor sounded like it was working a lot harder. I took it out and things are normal again. I printed this in PLA and after doing some tests, it seems like the glow in the dark PLA has too much friction when rubbing against other PLA, even when printed at .08 height.
I tried it again in PETG and it was slightly better. I tried to remix the part and increase the interior diameter a bit, and while that reduced the friction, it also created an edge that could be caught when sliding the filament into the PTFE tube.
I found that, for some reason, one side of the splitter is smoother than the other. Not sure why but I made that side the one for AMS filament and made the tighter side the one I'll use when printing with non AMS compatible filaments.
Either way, I found after many prints that that glow in the dark filament is abrasive and probably a very border line "AMS compatible" product. I have filament swap errors somewhat commonly using it, but adding anything other than pure PTFE tube in the path of travel makes it much worse. (edited)
Is it a problem using PLA instead of ABS/PETG?
@LucasVillalt_1030515 PLA will deform under pressure over (a long) time. Otherwise it's okay.
