Roller slingshot

I made a slingshot with two rollers to increase the shooting force. Print the body with screw supports, three walls with at least 30% infill, and all other parts with 100% infill. You can order a rubber band with a socket from China with a 5mm rubber band.You will also need 2 M3x20 screws, 2 M4x12 screws, 2 M4 nuts, and 2 M3 nuts.https://pl.aliexpress.com/item/1005006224376047.html?invitationCode=SStzWWt4eXNBSGUwZ01UeU5kZGV4NHVnRGZDMWN6WFI4dG1uaVU5N3VDd2pmdlBzNkVmWTlBPT0&srcSns=sns_Copy&spreadType=socialShare&social_params=61287287454&bizType=ProductDetail&spreadCode=SStzWWt4eXNBSGUwZ01UeU5kZGV4NHVnRGZDMWN6WFI4dG1uaVU5N3VDd2pmdlBzNkVmWTlBPT0&aff_fcid=fd2ab6da22b1453f902ba3f53fa6e198-1761127989829-04037-_EIC8YVI&tt=MG&aff_fsk=_EIC8YVI&aff_platform=default&sk=_EIC8YVI&aff_trace_key=fd2ab6da22b1453f902ba3f53fa6e198-1761127989829-04037-_EIC8YVI&shareId=61287287454&businessType=ProductDetail&platform=AE&terminal_id=dd2863b614774482ae996ad4e42888c0&afSmartRedirect=y
