Leaf Liberator

This is a flexible TPU tip meant for a 3x2mm fish tape spool. While it's best to clean your gutters and avoid the problem altogether this is meant to be snaked up a downspout to dislodge any debris that might be clogging it. Attach it with some basic 3-4mm zip ties.

I printed it on its side but you may also have success with standing it up.

Although this version worked for me I will be designing a longer segmented one that should be better at bending around corner pieces.
