SUP or Land-Paddle handle
This handle can be used for a stand-up paddle or a land-paddle - or any paddle! It was designed for a land paddle. The file provided here takes about six hours to print on a Replicator 2 at 20% infill, with 3 shells, and a layer height of .20 mm. (temp 230 degrees, with a raft and supports, at 80 /150 mm/sec.).
Land paddles start at about $90. Print this out, buy a replacement blade from Kahuna Creations, and a standard stairway banister pole from Home Depot, (cut it to about six inches over your own height in the store) and you've got yourself a land paddle for between thirty and forty dollars. Epoxy the handle in position.
Inner diameter of the handle (where the pole is accepted) measures 1.27 inches.
