rostock max v2 spool holders

These models are for replacing the Rostock Max V2 filament spool holder to reduce drag while printing. One model, which is labeled as "Nylon Holder", is specifically designed for printing Taulman Nylon spools which have a smaller hole diameter, and this directly fits where the stock holder goes. The other model is specifically designed for other standard sized spools. There are two parts to print, the "Just the Max arm" and the "Roller for Max holder". Then assemble them as shown in the picture, or just by using a 4 inch long 1/4-20 hex bolt with a washer and a nylon locking nut.
