There are plenty of drain snake STLs out there, but this one has bite. The design allows larger teeth while keeping the snake small enough to slip into drains. Prints in less than 30 minutes and works well at 0.20mm layer height. Fun facts:

• When printed, this tool is just under 20cm
• Prints great on Prusa MK3S and Prusa Mini
• I recommend PETG or other “less brittle" filament
• No brim needed for PETG on Prusa Textured sheet (YMMV)
