Đường hầm cho hồ cá (Fish Tank Tunnel)

This is a tunnel for our crayfish tank for him to be able to hide underground. It has ridged steps so this should work for other critters or fish too.

Dimensions:

• Bottom to top: 76.2mm
• Bottom to sand: 57.15mm
• Total width: 438.55mm
• Depth (front to back): 79.7mm

Printing details:

• I used Overture Matte Light Brown PLA.
• Printed on its side in 0.3mm layers (Prusaslicer 0.3 draft).
• In order for it to fit on my Prusa MK3 I cut it in half and welded back together with a soldering iron. See the included the 3mf of it pre-cut and plated.
• Another suggestion would be to connect the two models together in the slicer to make one smaller, continuous piece.
