    Hey , greetings from Belgrade
    Here's my interpretation of Instant Rufus. I was inspired by Joergs video and loading mechanism he designed. Also inspired by Instant Legolini 3D design.
    It's a pump action self loading repeating slingshot. It shoots steal balls, I made 2 versions 10mm and 8 mm. It's magazine fits about 20 steal balls.

    Have you thought of a roller gun design? Uses 100% of the length of the gun whereas with other designs the power stops at 2/3rds of the way. You can also get more power out of it because it stretches twice the length of a normal rubber

    Is this on Thingiverse? If so where abouts?

    Hey, I'm glad you like it. I was originally thinking about rollers for the bands but I am not sure how much force plastic would take. l tried silver and black bands an it works fine. Maybe I'll try adding rollers in next version.
    I will share stl files, but only trough email , I still don't want it to be shared publicly on thingiverse or any other host. PM me and I will send it to you

    I think it should hold up if you put a single metal bolt or something straight through the plastic and just have the rollers on either side

    Hey, as far as I am concerned this is a finished working toy, so I think I am done with this design for now. I've had some suggestions on how to make it more powerful but I think I reached the limit of what plastic can endure.
    If you would like to make your own PM me your email address so I can send you the link to the files.
