Key for opening shower drain (remix)

Key for opening shower drain. While renovating our bathroom, key was lost. I've recreated it from images in manual / brochure, and using drain cover measurements. 

NOTE:  It is created for Pestan Confluo Compact Line drain - but can be modified via included f3d file. 

Printing instructions: 

• Material: PLA, PETG, ASA, ABS (most likely any rigid material would work)
• Layer height: 0.2 or less
• Nozzle size: 0.4 - 0.6 
  (both work well with Arachne perimeter generator)
• Supports: Not needed.

Add small chamfer for more pleasing finish.
