Adderini - 6.5mm Sling Arm

prusaprinters

Edit** 8/8/23the 10mm theraband tubing is too tough for this poor plastic device.My advice. do not use the 10mm tubing.I have since downgraded to the 6.5mm red banding.I have redrawn the arms to suit.I will report back with hopefully better findings that the misery that I put myself through with the silver theratube…    simple double band arm for 10mm rubber. I tried it with two… wow… I put way to much strain on this poor thing.so I knocked it down to one band. it operates much better. perhaps you have a less powerful band.. but if you need it, its here for ya :P still way to much strain on the cocking lever, so I made a reinforcement addition, you can find it here: https://www.printables.com/model/514136-adderini-cocking-arm-lever-reinforcementEnjoy!  P.S.I needed ball bearings to hold the bands in nicely (just use rubbing alcohol to lubricate the insertion.) but the local hardware store did not have any for sale by the each. but what they did have that did work: 3/8 slingshot ammo (steel balls). [in case your in a pinch as well.]
