review / opinion
First example on Thingiverse of a single piece printable spool outside my research in the other thread. The ABS didn't warp which is probably due to the holes. Removable support material was not required. This spool is highly customizable on Thingiverse. It has holes for starting/ending the filament strand. The weight seems to increase a bit with single piece spools, probably around 50% for this one. There's room for more weight reduction by putting more holes into the spool hub and other solid spots. Very good work.
Here is a down and dirty calculator for this spool if you want to echo back how much filament your spool will hold. This should be accurate enough for government work. :-)
volumeall = width- cone_height ;
volumeCylinder = ((pow(outside_diameter/2,2)*pi*volumeall))/1000 - (pow (spindle_diameter/2,2) *pi *volumeall) /1000;
echo("<b>Max</b> Filament Volume is ", round(volumeCylinder)," CM³");
echo("Estimated Filament Weight is ",round(volumeCylinder*1.04)/1000, " Kg");
