This is a replacement of the stock aluminum handles for adjusting the Peak Design Slide strap length. Unlike the original aluminum ones, you don't need to worry about these plastic ones scratching your cameras. The handle has a raised lip around the torx bits to sink their heads to prevent any scratches from those as well.
I printed this at 0.1mm layer height with 0.25mm nozzle, but I am pretty sure it is printable with 0.4mm nozzle as well.
BEWARE: The Peak design slide has evolved over the years and my design is for one of the older revisions. I cannot vouch for compatibility with never models. Also is not compatible with the lite version of the peak design slide as that one uses much narrower belt
The author marked this model as their own original creation.
