AMS Saver Gen3 for X1C P1S

here's a link of my new design AMS Saver

https://makerworld.com/en/models/1092464

please check it out before you download this one

 

both of them work well for myself 

but I do improve my design skill from time to time   

 

---

 

thank you for the strongest support for all the boost and feedback keep this project going

our goal is a struggle free AMS system , so everyone can have a good sleep without worrying filament getting stuck

 

----

 

my filament got stuck all the time, it happened to me like once every few hours , thats the reason i came up with Gen1 design

It helps, but my filament still get caught once a while , then I collect all the feedback come up with GEN2, it works for me,

just some little things I didn't think is a big deal by the time when i design it, then here comes GEN3

 

this version took me a lot longer then expected

after my Gen2 , I had a lot less filament stuck issue , but there are few things still bother me

1. most large hole spool holder couldn't do well with gen2
2. the support of it blocked the indicactor lights
3. after a while some PLA printed chain become loose

here's my improvement for it

 

indicator lights are visible now, it work with or without transparent filaments

connecting chains become close loop, larger chain add more durability

heavy duty support , reduce the chance of moving chain

feeder nut is tight fit now, better protect for the plastic under it

 

the guide head can be swap , the original idea was upload this version with 10 types of guide head

i did save some messed spools / near empty spools / larger hole spools for test

however, i didn't got stuck by any of those spools, not even once

so…..there's nothing can be improve till I get some “bad” feedback from you

 

I'm sure there's room can be improve

if you run into any issues , kindly leave me a message , I'll try my best to figure something out

this AMS saver use 134mm PTFE tube, there's a cutting guide in print profile

also there's two different guide head in print profile might fit your spools

 

Boost Mehelp me keep improving this project, thank you :)

 

 

push the feeder nut in, it should hold the plastic tight

 

 

 

 

update Dec 27 : scale feeder nut to 100.4% for PETG printing, I also tested with PLA as well

update Dec 27: Add tested silm support for people needs to change desiccant box frequently 

( special thanks to noxonix for this one)

 

update Dec 27: 

 

due to different shrinkage of different filament you are using , it might not fit your AMS perfectly 

please do a fitting test before you print 4 sets

 

enlarge it to 100.4% if its a bit loose

enlarge to 100.8% if it can move around 

 

I got both tested with 5 different types filament , it becomes very tight on my AMS, but might work better on yours

 

update Jan 04: upload new guide head oneside PTFE tube for tight full spools 

                           upload two PTFE guide head print profile

 

Update Feb 20: upload a 0.2mm hole compensation print profile for larger PTFE tubes ( use this one if your PTFE tube couldn't fit )
