Instructions See the movable 3d-images and technical drawings in the PDF for details. (such as belt-size) You can use the free Xpress-version or a 30 day trial of Alibre Design to change this parametric design (e.g. for different belt-sizes, countering of stronger or weaker warping,...) The STL is already oriented to be printed on a Thing-o-Matic. At the moment my ToM has warping-issues due to a new plastic that I am slowly getting working. Thus the design contains some carefully placed holes and a wider base to counter warping by design already. You can still reach all buttons and connectors with this clip (carefully rounded holes to reach the input- and output- level + and - buttons, access to the headphone-jack and even a hole to not obstruct the speaker.) You can even mount your H4n onto something without taking off the belt-clip first. (Most of these 1/4" camera bolts you get in shops have a 1/4 threading)
