2x filament Spool adaptor

I needed two colors on short notice so i used Amazon prime two day free shipping for some signstek filament (claiming to fit Makerbot 2 ), when they arrived I learned they didn't fit the 2X! My lovely wife (who got me the 2X for Christmas ) started to box them up for return--
I siad let me see if i can make an adaptor. it took 5 tries using a 15 yr version of Cadkey I had laying around but it was great practice!!
