The modified spool platform mount is designed for installation above the printer, compatible with Prusa and potentially other models. The original GP hook had some issues with holes and double faces, but they were fixed. The mount can be placed on the upper part of the printer's side with electronics. The size of the platform clip was adjusted to fit between the z-axis motor mount and main structural frame. Additionally, a filament guide is mounted on the other side of the main frame. The design is also available on Thingiverse at http://www.thingiverse.com/thing:122954. A custom filament guide allows for horizontal mounting, requiring a toggle bolt with two nuts (4 inches bolt, 3/16 nuts), a matching hex nut, a printed spacer or insert for the filament spool, and a vinyl or plastic cover that matches the spool. The components serve to keep the spool steady with minimal friction, prevent unscrewing of the toggle bolt, reduce spool wobble, and minimize friction between the mount and the spool. It is advised not to unwrap a filament spool until ready for loading into the extruder. Extrusion issues may arise, such as the first problem solved by this spool mount, binding up on long prints. Another issue related to tightening the bolts and springs on the extruder itself. The last issue concerned increased build height necessitating a new extruder mount and learning to print with ABS. A modified design from Thingiverse was used, available at http://www.thingiverse.com/thing:122560. A spacer/washer design was also generalized into a module utilizing the cone property of the cylinder, found at http://www.thingiverse.com/thing:1224093.
