1kg plastic spool adapter for the Filament Spindle MK1 Box

Do you have a lonely Filament Spindle MK1 Box sitting under your printer recently antiquated by the nifty new 1kg platic spools that Makerbot is now selling? Me too ... so I set about creating an adapter that would allow the FSMK1B to use the new spools. My situation was complicated by the fact that I had partially destroyed my FSMK1B trying to reload it with the second batch of plastic that I had bought for my printer (this was the old 5LB style). In my adapter design I tried to address several of the things that made me want to pull my hair out about the FSMK1B original design :

1.) The whole flange assembly (the round disks holding the plastic) had to be removed from the box to add more plastic.

2.) The top flange of the spindle was almost impossible to attach.

3.) The top flange was held in using screws instead of a quick release latch.

4.) The spokes seemed a bit flimsy and were difficult to screw together.
