Salamander Designs Chameleon Collection Aluminum Extrusion Twist-in Velcro Holder

The Salamander Designs extrusion appears to be inch-based, as the outer dimensions are 1" and 2". It looks similar to 80/20 10-Series as well. However, I found the t-track dimensions are larger than 80/20 10-Series. I'm not sure if their extrusion is custom or where they get it, but I had to adjust the dimensions for this Velcro strap holder to mount properly.

I exported two versions of the holder. One version excluded the original designer's final feature, which removed material from the under side of the t-track anchor. The second included the subtraction feature of 0.25mm. Both fit the extrusion, but the first is a tight fit and does not slide easily in the track (useful for vertical members), and the second is a loose fit, and slides in the track well (useful, but not for vertical frame members). I decided to include both in the event that someone wants both fixed and sliding versions.

To easily distinguish between the two versions, I put a “T” on the Tight version, and a “L” on the loose version in the attached 3MF file that includes both versions in one file. If multi-color printing is not an option for you, simply remove the feature in PrusaSlicer.

Printed at 50% gyroid infill, 0.2mm layer height, 0.4mm nozzle.

Thank You to the original designer for providing the native Fusion 360 file! This saved a lot of time not having to re-make the part in another CAD software.
