This is a remix of jayziggy's awesome original model. I made the following modifications: Scaled the original to .001 in Netfabb so that the object would seem to be in mm units rather than µm. MeshMixer was then used to add some breakaway supports so that the ends of the strap clip would print better on my single-extruder printer. While in Meshmixer it seemed worthwhile to adjust the mount point to add a space for a loosely-captive nut. I found it difficult to get right the size or the cavity for the nut within that application, and instead went for a loose cavity with little protrusions around the edges to hold the nut in place. A timelapse of a print can be found at: https://vimeo.com/96028830 Edit 08/14/14 -- by request, I've added an STL file that's sans support (all save 1 that I couldn't easily remove). I've also added the Meshmixer files for the original and sans-support version. Edit 08/15/15 -- added greycat001's optimized and supportless version, named "GP_ScubaMount_v2.3_nosupport fixed.stl"
