3D BOATY

3DBoaty is a 3D model designed for testing 3D printers. It's a small model, only taking 16.5 grams of material to print. There is also a scoresheet to measure how good your Boaty came out and compare it with others. 

Step file Included

What the Boaty Tests:

• Bed adhesion - Starting from just 6 small feet, good bed adhesion is a must for a successful print.
• Overhangs - The arch in the 3 frames of the Boaty and the arch on the arms.
• Bridging - Tests your bridging capabilities up to 25mm.
• Top Surface Quality
• Hole Precision
• Max Flow
• Small Details
• And for an added challenge, speed. Test to see how fast you can print one. Sub 10 min Boaty?

Scoresheet: (Total 21 points) 

• Bed Adhesion (6 Points) - -1 point for every foot that loses contact with the bed. -6 points if you need to use a brim.
   

• Bridging test 1 (5 points) - Check the underside of the Boaty, -1 point for every 1-3 loose strands. Like in the image. (EX: 4 loose strands is -2 points)
   

• Bridging test 2 (2 points) - You should be able to clearly see through the gap on each side of the Boaty. -1 point for each side you can't see through.
   

• Small Details (1 point) - You should be able to read the small text on the back clearly. 
   

• Hole Precision (2 points) - You should be able to fit 1.75mm filament through at least 2 of the holes on the back side of the Boaty. -1 point if you can't fit the filament through 2 holes. -2 If you can't fit filament through any holes. 

• Max Flow (1 Point) - If your max flow rate is too high, there will be a transition from matte to shiny going from yellow to green. -1 point if the transition is visibly noticeable. 
   

• Overhang test (3 points) - On the bottom of the Boaty there are 3 arches to test overhang performance. -1 point for every arch with drooping overhangs. 
• Top Surface test (1 point) - The seat of the Boaty should feel smooth to the touch. -1 if it is too rough. (over extrusion) 

Speed Boaty Challenge:

The goal of this challenge is to see how fast you can print the Boaty while still resembling a Boaty. You can DM me here with your submission. I will only be keeping the top 5 entries.
