Parametric Umbrella Holster

This is a umbrella holster that I designed for a specific umbrella I owned and only that specific umbrella but may be applicable to other umbrella. It is also designed to clip on to a MOLLE backpack.

It is parametric, so it's possible to customize the the holster to work with your umbrella or to your specific backpack. 

Printing: 

I used standard PETG profile that came with prusaslicer at 0.20mm layer height. It should requires no support or brim.

Usage: 

Customizing:

In order to modify the umbrella holster's parameters and then generate the resultant STL, you should be using OpenSCAD.

The umbrella holster is made up three distinct part: the umbrella ring which clips to the umbrella, the neck, which is between the umbrella ring and the clip, and the clip which clips to a MOLLE system such as a backpack.

Ring:

• ring_r - Radius of the umbrella ring.
• ring_h - Height of the umbrella ring.
• ring_t - How thick the umbrella ring is.
• opening_t - The gap in the ring which allows the clipping to an umbrella. It can be made smaller or bigger depends on how secure you want to be or how harder it will be to clip.

Neck: 

• neck_d - How long the neck is. The clip will be on the end of the neck.
• neck_w - How wide the neck is which also determines the clip's width.
• neck_h - How thick the neck is. My preference is to make the neck as thick as the umbrella ring, but you may choose otherwise.

Clip:

• clip_thickness - Determines the thickness of the clip's two clamps.
• clip_spacing - Determines the spacing between the clip's two clamps.
• clip_height - Determines the height of the clip from the clip's base, not including the end of the clip.
