Description

PDF

Here is a external spool cradle, made into the side panel for the ams drawer kit. 

It works amazing, is parabolic and self centers. 

You feed it and forget it. I use these more than the AMS's, it's far more reliable and saves the AMS for multi-color printing. This also works with TPU and the AMS does not. 

It's nice as it keeps the external roll at a similar height as the ams. It allows me to stand during  all filament swaps. 

Filament cup/bell up front makes it a breeze to load/unload. The reverse Bowden tube snug press fits into the cup - use a rag to insert it

No screws or hardware needed (other than *4 608 skateboard bearings), you tap it together with a wood handle/mallet/deadblow, just like the drawer kit. Its a tight fit, and stays together. 

This is my first remix, combining different projects - Please let me know if you all like it! 

Thank you!

*Recommend 4-5 wall loops & top/bottom

-My Settings-

0.28LH 220degrees PLA+, ~200mm/sec, 4 loops, 4 top/bottom, 15% Gyroid, side plate print time = 4:38hr

-Updates-

Aug 3rd 23 - updated the project - v2 added (15 degrees less angle on filament bell, double checked all files are current) - Added the individual STI Files to go along with the entire project. (Easier to just load the multi-plate project)

Aug 5th 23 - Updated the project files to v3 - Cleaned it up visually a bit and added a bit more strength in the side panel. These have seen 23hr a day usage with zero issues. 

Aug 11th 23 - Added optional Smooth roller. You can pick a pattern textured or smooth roller set.
