Printrbot Metal Simple Spool Holder

Fits on the top of the Printrbot Metal Simple. I recommend adding a brim when printing to prevent curling.

Spool v2 does not include the filament feed line. I've found that it is not necessary and it can make the part harder to print.

Spindle v2 has a solid core. You can choose settings within your printing software to decide how the interior is filled.

Update: Printrbot is now shipping their assembled Simple Metal machines with the handle and a very nice spool holder.
