Thread Die Holder

thingiverse

Convenient holder for thread cutter dies. Requires up to eight M3 x 10 mm screws and nuts. Pull the nuts radially into thir hex recess with the help of the screws (nut with flat side up, see cutaway 3D drawing). ==================================================================== Update 5 August 2023: I broke the previous holder while cutting mild steel because I had printed it with only 2 peripheral/loop and 2 top/bottom layers. Further, the vertical insertion of the nuts proved problematic in that some nuts turned freely after their seat was damaged during forceful insertion of the nut. So I redesigned the holder for radial insertion of the nuts into a tight hex recess and printed it with 4 peripheral/loop and 3 top/bottom layers. Hope this helps. Update 21 July 2023: - Added slots between die and nuts. While dismounting, you can now observe which screws are still enganged and which are not (see picture #2). Update 15 July 2023: - Eight instead of two mounting screws. Now you may possibly use all of any die's mounting holes. - Slightly stronger nut backrest requiring slightly longer screws (M3 x 10 mm instead of M3 x 8 mm) and slightly larger outer diameter (82 mm instead of 75 mm) ==================================================================== It is designed for a maximum die diameter of 30 mm. Larger diameters may require enlarging the outer diameter and possibly further changes (M4 or even M5 screws and nuts?). And larger diameters may require torque impractical for this tool, i.e. you may rather need a classical holder with a pair of long bars. If you require a specific size (outer diameter up to 30 mm and height of the die) send me a message (you may need to have a Thingiverse account for this). I will compute and add your specific .stl file. Or you may create the .stl file on your own according to the instructions below. I optimized rendering time, but it may still take a minute or so to compute the minkowski() rounding function. As always I include the OpenSCAD source file for you to adapt and/or improve: - Download and install OpenSCAD from https://www.openscad.org - Launch OpenSCAD and open the enclosed OpenSCAD source file (/File/Open). - Amend the parameters at the top of the file or even amend the code. - Save your changes (/File/Save). - Render the design (/Design/Render). - Export the rendered design e.g. as a .stl file (/File/Export/Export as STL). - Slice and print.
