Over forty real parts sorted by their largest dimension: what prints at 180 mm (A1 mini), what only fits at 256 mm (A1) and what fits on neither.
Each bar goes from 0 to 320 mm, by the part's largest dimension. The red marks are 180 mm (the mini's limit) and 256 mm (the A1's limit).
The mini prints
Up to 18 cm in every direction. The A1 does all of this too.
Only the A1 prints
From 18 to 25.6 cm. On the mini, only by cutting into parts.
Neither prints it whole
Over 25.6 cm. Possible in glued or interlocking parts, on both.
"File size" label: minimum printer size reported by the designer on Prinnit, checked on 2026-10-01. The rest are typical sizes of these parts on model sites (Printables, MakerWorld), rounded: the file you pick may be larger or smaller.
