Dr Eggman, a character from Sega's Sonic the Hedgehog series.

Doctor Ivo "Eggman" Robotnik is the main antagonist of Sega's Sonic the Hedgehog franchise. Eggman is a mad scientist who seeks to steal the mystical Chaos Emeralds, defeat Sonic the Hedgehog, and conquer the world.

I chose to model the earliest classic version of him, as he has changed quite a bit over the years.

No supports are required. See notes for printing considerations, considering that this is larger than my typical model.

If you have the proper filament colors, no painting is needed.

As presented, Dr Eggman is mostly in proportion to my previous Sonic and Tails models.

The assembled model with the base is 270mm long x 225mm tall x 220mm wide. All individual parts fit on smaller print beds, using the Prusa Mini as a guide.

Enjoy!

**Printing and assembly tips**

Printing tips
1 - This model is larger than my typical models, please note the size that is posted in the beginning of these notes.

2 - There are some pieces that may need brims:

* I used brims on:
hand_right
hand_left
arrow_black_extra

If you use a brim on arrow_black and or arrow_yellow, be sure to clean the brims thoroughly for a good fit

3 -The following point is applicable to all my models, but more so for this one:
When removing parts from the printer bed, it's a **VERY** good idea to place left/right parts into separate containers to help with the assembly process. Sometimes the difference between the left and right parts is very small but it is still worth keeping track of them and assembling them in their proper place.

4 -The arrow_black and arrow_yellow parts are presented in the order for assembly. They may seem similar but each part is unique. Personally I put them on a piece of tape in the order I took them off the bed. The bottoms are hidden, so you can also mark them there as well. For printability, arrow_back_extra is positioned upside down. As per the diagram, this is the black tip of the arrow.

5 -The parts ship_front_black and ship_back_black print easily but using my go-to printing parameters I had some warping off the bed. Consider typical solutions to avoid this such as cleaning your bed before printing these parts, use a higher print temp, adding helper disks to hold the corners of the parts down.

Assembly tips:

1 - Take your time gluing the model together and enjoy the process. Give some thought into which parts to glue together as groups and then gluing the groups together. Let the glue for each group set completely before combining groups.

2 - I used 3D Gloop and E6000 to put this model together. Each type of glue has different pros/cons and I found that 3D Gloop was far easier to use than superglue (for me). The E6000 sticky glue that I also use allows more time to position parts and is still the best for smaller parts. For both glues using a smaller amount is usually better than more glue.

3 - When inserting the arrow parts into the ship, start from the back and work your way forward.

4 - The steering has just a slight indent into the ship, so, I found it simpler to insert the steering after Eggman is inserted and just shift the steering into position under the hands.

4 - The flame_red and flame_yellow fit only a certain way. Do NOT force the parts, instead rotate the parts to find the perfect fit.

5 - I've divided the assembly diagram into multiple pictures for clarity, However, assembly should be straight forward as long as left/right parts are separated and the diagrams are referred to closely, especially for the wings.

6 - Refer to the assembly diagrams in the pictures section as well as the uploaded pictures for putting the model together. The model is meant to be glued.

Do not hesitate to ask questions, feedback is essential to making better models.
