Unlimbited Phoenix Hand tensioner box and pins
Description
**TENSIONER BOX** I re-modeled the tensioner box in Fusion360 to have a better and smooth mesh. Fusion360 source file is 100% scale.     <br/><br/> **TENSIONER PIN** I don't like original design because I found it's faulty when I printed the "threading ribs" Here below a section of the hole:  The highlighted features can't be successful printed without support: I modified the hole section to be more easy to be printed without supports:  Then I made several tests to find the right interference between screw and thread. I found that for an M3 screw, the best is 2.7 mm. This diameter has to be adjusted in the sketch named **interference** in Fusion360 file. The file is scaled 100%. If you have to increase the scale in the slicer, you should decrease the interference diameter in order to keep more or less the right interference once printed.   Then I tested that interference is enough to bear some weight. Up to **two kilograms** are ok!
