Replaces the stock injection moulded slider clamps of my He3D K280 kossel delta; the stock item is actually fine, but this version has a simple adjuster mechanism, and is sized for a 9mm belt upgrade I made.
Models are provided for 40 and 42mm pins, plus 6 and 9mm belts: A stock K280 has 6mm belts and 40mm pins.
The stock He3D 4 roller carriage backplate design is actually quite good, and I think the 20x20mm spacing for the mount bolts is common to a whole bunch of Kossel designs.
Use support for the pin arms and slider bracket. I originally printed these in PLA and they worked fine for a year, But I re-made them in PC-ABS (horrible material to print with, but very strong and stable) when I updated the design.
fit both pieces but only fully tighten the upper bolts, leave the lower loose enough so the slider can slide. Then fit the belt, making it tight'ish on the clamp. Finally tension the two pieces with a thumb and finger on the ends to a firm tension on the belt, don't go mad.. but it's OK to squeeze reasonably hard, the belt should thrumm like a double base when plucked.. Finally tighten the lower bolts while maintaining the tension; and after a few hours of printing and settling in it's a good idea to re-tighten and check everything.
Finally; The scad file is also there if you want to remix, laugh at my mistakes, etc. OpenScad 2016.11 or later is needed for the clamp to render properly.

Yes

Notes:
Printed in eSun's PLA+, but any good constructors PLA should work.
You need (buildplate only) support for the clamp piece, and it helps the lug arms on the main body come out well too.
