This is a remix of the classic Calibration Cat (Cali Cat by Dezign), but scaled up to 800% (8x) and split into multiple parts to accommodate common build volumes of printers (220mm x 220mm x 250mm).
Pieces fit snuggly together for easy alignment and gluing. At a layer height of 0.2mm, 7.5% infill and two layer wall thickness, printing this is about 30g shy of a 1kg spool. See video.
If you are curious what prompted me to create this see these subreddits:
