Hoop Booster

After finishing your print you need to press-fit metal hoop tightener into this part.
It is necessary to heat the inner cavity of the printed handle with an air gun with a thin tip on it and then insert the metal hoop tensioner into the holder cavity with good amount of force. Do not heat the metal handle of the hoop - this can damage the parts of the hoop. Heat only the printed part.
Please give a feedback if it works for you.
