PO-20 Symbol buttons for Pocket Operator case

Buttons engraved with PO-20 model symbols. Compatible with the Pocket Operator case: http://www.thingiverse.com/thing:1375818

• The "v4" version are the same buttons as included with the Pocket Operator case. The details of the symbols will need a very small extruder when using FDM. Extrusion diameter of 0.3 mm or smaller recommended.

• The "v4wide" version of the buttons has a larger diameter (0.5 mm), less fillet and slightly larger symbols. These are intended to be used when the both case and buttons are made with SLS printing. Using FDM printing these will likely not be able to move freely in the button guides of the case.

Note: A version of case, buttons and light guides optimized for SLS/SLA printing also available at shapeways: https://www.shapeways.com/shops/cdb (rendering shown as cover picture).

Update Dec. 2020:
Added files with just the 5 generic symbols and just the 16 PO-20 symbols for easier printing in separate colors.
