Meet Our Hero’s Mech(s)

 Stieg Miner pilots a HMC-14 Hermit Crab, but which model to use for the job? 

They’re two different .stl’s, produced by two different, high-quality Etsy manufacturers. 

I love them both, but I am stumped on which one to feature in our story. 

Maybe both? Perhaps one could represent an HMC-13, and the other an HMC-14?
