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

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.

This is a great design, exactly what I wanted, but couldn't design as I have no previous building experience. Could you please share the design to make same thing from wood? My email is drjjani(at)gmail.com

Don't know if you still use the forum, but I just joined after seeing your post. If it's possible to still jump on the bandwagon could you please send STLs for it?
