A smooth 2-in-1 PTFE adapter for using an AMS, rear spool holder and a dual spool drybox or secondary spool holder together on a Bambu. Updated design with PTFE tubes slid inside the adapter as far as possible to minimize filament contact with the printed part. Tapered outlet to toolhead PTFE to eliminate filament snagging on the edge of the PTFE. This is an updated design of my previous version.

一个光滑的二合一PTFE适配器，用于在Bambu上同时使用AMS、后线轴支架和双线轴干式箱或辅助线轴支架。更新的设计使PTFE管尽可能滑入适配器内部，以最大限度地减少灯丝与印刷部件的接触。锥形出口到工具头PTFE，以消除PTFE边缘上的细丝钩住。这是我以前版本的更新设计。

BOM:

-printed part

-2pcs PC4-M5 pneumatic fittings (like these, for example)

Assembly:

-check with a piece of filament that the bottom hole of the “Y” (the one pointing towards the toolhead) is not too tight, deburr with a 2mm drill bit if needed

-insert magnets

-make sure a 4mm bowden tube fits all the way into the four branches of the Y along with the shallow pocket on top connection, test this before threading on the pneumatic fittings

-thread the pneumatic fittings on (if using PLA don't use excessive force, they don't need to be super tight)

-insert adapter on PTFE tube coming from the printhead, make sure it's seated all the way

-insert other PTFE tubes, make sure they are inserted all the way

-enjoy!

BOM：

 

-印刷部件

 

-3件PC4-M10气动接头（例如，类似于这些）

 

 

装配

 

-用一根细丝检查“Y”（指向刀头的那个）的底部孔是否太紧，如果需要，用2mm钻头去毛刺

 

-插入磁铁

 

-确保一个4毫米的波顿管与顶部连接上的浅口袋一起完全安装到Y的四个分支中，在拧上气动接头之前进行测试

 

-拧上气动接头（如果使用PLA不要用力过大，它们不需要超紧）

 

-将适配器插入打印头的PTFE管上，确保其完全就位

 

-插入其他PTFE管，确保它们一直插入
