Large and XL Slingbow arms for the Adderini

cults3d

I made some large and extralarge arms for the Adderini similar to my extended arms for the sliding Legolini. One warning though: Longer arms mean more stress to the mounting parts on the Adderini. You should NOT use the longer arms to mount rubber in similar strength as the original double folded Theraband Gold in 6 cm width. Elongating this rubber longer than in the original Adderini design means both more draw weight and more stress to the structure. Using PLA might be fine in the first place but I went the PETG route for the arms and after printing out the large and extra-large arms, I went for the large arms simply because XL seemed too long for my intended rubber tube. YMMV... Main purpose of those longer arms compared to the original arms: Giving you more draw length to adapt may be for the usage of 3 mm PP rope instead of a bowstring. You can also fineadjust draw weight by playing around with your string length versus rubber length.
