Sonic, the title character of Sega's Sonic the Hedgehog video game franchise, created by Naoto Ohshima and Yuji Naka.

This is a onepiece version of Sonic based on my multi-part Sonic model that I've previously posted.  

Since I do not have an SLA printer, I teamed up with maker Kyler Stern to do the printing and painting.

I converted my multi-part model to a onepiece model for SLA and FDM printing.   Kyler then proceeded as follows:

Sonic: Decrease size from original to 3 Inches tall.
Scale: X: 2.39, Y: 2.11, Z: 3.00 Inch = 47.72% of original size
Printer: Anycubic Photon M3
Resin: Anycubic Water-Wash Resin+ Grey
Layer Thickness: 0.05 mm
Partially hollowed. Hand, feet, 5 lower spikes were not hollowed. Basically this allowed the model to be hollowed right down the center and the top three spikes.
Print time: 5 hours

Note: Something important to call out regarding print time.  Kyler has his screen power set to 80% power. This increases print time significantly but extends screen life. This might be important for individuals going forward.

Other notes regarding the supplied STL file:

For FDM and SLA printing, size the STL file as needed for your purpose and add Slicer supports.

Enjoy!
