I hate it when you get a batch like that and run out of one or two colors and have to buy the whole batch again to get the discount and have scads of the other colors hanging around.
Not sure what the "+" stands for. Opened a box of the black and used it to print this little nut driver handle I drew up on F360 and used my same old pla settings. Printed up the same as regular pla it seems.
I embedded a magnet in this to hold the nut driver in. Works great.
