These are all the 3D printed parts used for OPL Studio.  You can use these to customize you OPL Studio or replace a part if something breaks.

To get the best results:

• Print the enclosure side upside down with supports under the 7 screw posts
• Print the stylus holder with organic only for the overhang where the stylus enters
• Print the LCD holder legs upside down and print a copy that's mirrored along the X-axis
• Print the LCD bezel upside down
• The LED spacer is best printed on its own as it may become too brittle when combined with other parts. I found a brim not to be necessary, but you can add it if needed
