In printing with Polycarbonate I decided it was time to create a Y-Splitter so I can leave the PC spool in the external drying box. This way the humidity level will stay well below 20% and I won’t have to plan so far ahead to re-dry each time I want to print with it.
This is my take on a Y-Splitter.
- I made the main body a hex shape. This gives a flat surface to print from.
- Decided to make the ends of the Y-Splitter to work like a Pin Vice. This design eliminates any tolerance issues; PTFE tube OD’s don’t measure exactly the same for reliable press fits. With a Pin Vice scheme, regardless of tube OD, as you tighten the nuts the PTFE tube gets held firmly.
- The Y-Splitter and Nuts require no supports, skirts or brims or anything special to print. But, do make sure your print surface is clean, I used the Bambu Lab textured PEI build surface and the Bambu Lab print surface adhesive (the liquid version).
- The Y-Splitter shown in use is made white ABS but, I elected to print the bottom of the direction arrows in black for good contrast.
