Printed with PETG, 0.4 mm nozzle and 0.2 mm layer height.
Used tree supports for the head to hold the snout and back spikes, for the body to hold the arms and for the leg to hold the small bump.
You can place support blockers for the PCB holes and overhanging shell on the legs if you'd like, they can be printed without supports.
The author remixed this model.
Upscaled to actual size so you don't have to do it in the slicer.
Removed one back spike and made space for its snout, the clamps on the head fit into the body slot perfectly now.
The holes for the Nano Shield were misaligned by 2 mm for me, I moved it so the Micro-USB can be used on its side.
Not a fan of gluing parts together, I made an extra fused version with its tail and body if you don't mind the extra material for supports.
