Need parts for your Bungee Grabber for your Longarm Quilting machine? This design will allow you to print everything you need minus the (2) torsion springs and (2) M4x6x6 heat set threads.
I have never located a source for the springs.
I used the inserts I bought here (https://www.amazon.com/dp/B08YYGRCBG?psc=1&ref=ppx_yo2_dt_b_product_details) from amazon.
Once inserted, the parts are basically identical to the original.
The author hasn't provided the model origin yet.
