Summary

I really liked this idea, but wanted a little larger holes than 3.0mm so I did not have the thread the screws in. The wings had to be a little wider to accommodate the slightly larger holes, so I traced the profiles in DraftSight and created the remixed version in openscad. I checked the original source https://www.youmagine.com/designs/stackable-fuseholder to make sure I could remix this. I have not printed this yet, but did overlay the originals with this & they look like they match. I used the car fuse model from the openscad file: http://www.thingiverse.com/thing:505360

There are 2 main variables you can change, P_Type& Orient.
Set P_Type = 0 or 1 //0 = Original profile, 1 = New Wider Wings and larger holes
set Orient = 0 or 1 //0 = Original Vertical Print Orientation
//1 = Print Flat orientation

There are also 3 array variables that are used to distinguish which profile you are using. If you want your hole diameter different, you can change A_Hole_OD index value.
3.0 corresponds to the P_Type = 0 & the 3.6 corresponds to the P_Type = 1
