Huey edge slide.

After 3 versions, the edgeline should be rock-steady, both mechanically and version-wise. I had to rework travel on one axis initially, but pinpointing the cause proved challenging. Installing dual bearings might have helped, though, or moving the belt attachment inline with the shaft may also have played a role – either way, I'm still unsure. A video demonstrates the edgeline: http://youtu.be/0r5rYepdS4I The instructions below detail assembly and requirements: 1. Print both parts in vertical orientation for best results. 2. Each part features integrated supports to simplify removal from the print bed. Printing materials like ABS can introduce distortions – I had this issue firsthand – whereas PLA yields superior results. As a bonus feature, an M3 flower nut is included, allowing you to secure the shaft with extra stability; however, mine were so tight that it's unnecessary. The optional nut measures around 5mm in diameter and comes in at least two sizes for versatility.
