how to fit thicker spools of filaments

I still have LOTs of ABS and PLA from the old Thingomatic days. That was my only printer before the N2.

I am not sure if the current Makerbot filaments are on thinner spools. But my old Makerbot filament spools are too "thick" (or is it wide) to fit on the internal spool holders. If I put a roll on the holder close to the LCD, the right door won't close and rubs on the edge of the spool holder. Is anyone having a problem with this? My old Makerbot spools are 4-5mm thicker/wider than the Raise3D ones.

Is it just me? or am I not positioning them correctly on the spool holder?

thanks!

I have some larger spools too so I just leave the door open sometimes. If the holder doesnt fit, just simply download a spoolholder design from thingiverse (i used this http://www.thingiverse.com/thing:1001925) and resize it or cut it in Ideamaker. I hang one of this in my machine.

Found the solution to jamming filament spools (AND extruder jams): the filament spools are wound too tight, which causes the spool discs to spread slightly and therefore rub or jam on the printer (MakerBot 5th Gen). I even encountered this problem on factory-wound spools - some would fit, and some would jam. If a spool is jamming, re-spool it looser. This solved every jam. The over-wound spool problem was also the source of my "extruder problem": the over-wound, widened spools rubbed on the printer housing, creating too much filament travel resistance, causing the extruder mechanism to start skipping. The extruder was fine: using properly loosely wound spools instantly fixed the extruder skipping. Again, all the problems arose from the spools being wound too tightly, causing the spool flanges to spread out and rub or jam. Happy printing!

Replying to the list this time.

I created a spool holder as well (to deal with wider spools and/or spools with a smaller center hole):

For PLA, I run with the door open. For ABS you really want the door to be closed, so I'd probably put a hole in the door (so that the filament can still get to the feeder hole) and use an external standalone filament holder.
