Spool Roller for Rostock Max v2

thingiverse

This thing is a spool roller adapter for Rostock Max v2. It utilizes spool rollers from http://www.thingiverse.com/thing:119016. I designed this because I use spooled filament with 50mm center bores and it simply works! The new adapter fits securely in the same position as the stock spool arm. Furthermore, yes, this allows the user of larger spools from Makerbot, you know, those that do not fit your Rep1 or Rep2 anymore. NOTICE: This .scad file necessitates the spool arm .stl file from http://www.thingiverse.com/thing:213252. Make sure to download that first, rename it Spool_arm.stl and place this .scad file in the same folder before compiling. Instructions Required parts: (1) 5/16"x5-1/4" bolt (6 inch will work but will stick out a bit) (2) 5/16" washers (1) 5/16" Nylock Instructions: Print the adapter on its end with supports. Clean out the supports. Print the 50mm roller from http://www.thingiverse.com/thing:119016 Insert the bolt through the adapter and add the washers. Insert the roller over the bolt and thread the Nylock. Tighten until the roller does not slide back and forth but still rolls freely. Note: You can print any size roller you want provided it is the same height as http://www.thingiverse.com/thing:119016 and has a 5/16" bore. The roller should not bind on the bolt.
