This model is designed by peaberry (http://bit.ly/2GI3aU6), thank you very much for your great support. For details, please see the description below:
Snap on end caps which fit the top of each tower on the "Anycubic Kossel Linear" printer. Intended to stop dust collecting, and to cover the limit switch wiring and idler wheels. The printer has 2020 extrusions, and the caps may fit other similar Kossel Delta printers.
V1 printed fine and is what I'm using, but V2 has a 1mm tweak to the radius of curvature which should theoretically make it fit more flush to the outer curve of the tower caps.
Straight off the printer, I found this was a pleasing "snap fit" into the channels in the extrusion and easy to remove and replace.
Printer: Anycubic Kossel Linear
Resolution: 0.2mm layer height, 0.8mm shell thickness
Infill: 0.6m top/bottom, 10% fill density
