The armband is a 2 straps that are both strong and very flexible that is optimized to print in Ninjaflex filament. The straps are held in place to the bottom of the box by pressing the tabs through the loops on the side of the enclosure. The two straps are held together by pressing the two pins through the hole cutouts.
The enclosure is a 2-piece design that is optimized to print in PLA material. You have the option to print the enclosure to include the hoops for the armband or without. minipov-bottom-armband.stl includes the hoops, minipov-bottom.stl does not.
Carefully use Flat Pliers to remove the support material on the minipov-top.stl part. You will need to remove all of the support in order for all of the components to fit inside the enclosure.
Ensure you follow the instructions for assembling the minPOV4 kit! The only different step you'll need to do is soldering the wires to Power. Don't solder the 3-AAA battery cable to the miniPOV4. Instead we'll be using a JST cable with female connector.
Shorten a JST cable with a female JST connector to about 40mm long. Strip the ends of the positive and negative wires and solder them into the RED and BLACK pins of the MiniPOV4.
Wrap it in gaffers tape to protect the surface from being punctured or damaged (they can easily get nicked, be careful!). Carefully insert it into the minipov-top.stl part with the power cable facing away from the potentiometer.
Insert the slide switch into the enclosure by wedging it through the clips slide-ways. Carefully use an x-acto knife to loosen the tolerances if needed. You can press on the outside of the enclosure to insert slide switch cut through the cutout.
Insert the MiniPOV PCB into the minipov-top.stl at an angle with the USB inserted first. Ensure the JST cable isn't in the way of the potentiometer. Position the PCB into the enclosure.
Carefully flatten the tip of the minipov-potknob.stl with flat pliers. Line up the tip of the minipov-potknob.stl with the blue potentiometer on the miniPOV. Carefully infix the knob into the cutout of the minipov-top.stl part.
Insert the tabs at the ends of armband-tabs.stl and armband-holes.stl into the hoops of the minpov-bottom-armband.stl part by pressing the tabs through the loops on the side of the enclosure.
