Another KX2 Spinner Knob

thingiverse

There have been a number of Elecraft KX2 and KX3 spinner knobs posted but I've seen that a lot don't fit and other things. I have a KX2 and decided to make myself a knob with a finger hole for spinning. This may be a work in progress as the spinner hole isn't the best resolution but it's on the KX2 and for me it works just fine. I've included both the Fusion 360 f3d file and the FreeCAD .step file so anyone that wants can edit or customize it for themselves. There are two ways you can print this .. Top down on the print bed or bottom down. If you print it bottom down, I suggest Cura's "Tree Supports" as there are a number of things that will need support unless your printer is REALLY good at bridging. (Mine is OK, but not good enough for this size gaps.) Printed on a Creality CR10, V2 (CR10V2 not one of the selections in Print Settings). I printed this one in "Draft" mode with speed at 110mm/sec with a .4mm nozzle and that's the reason the resolution is not the best. Takes a bit over 45 minutes to print at this speed.
