Pneumatic Assist Trolligy Pump

I wondered why I hadn't seen this done more often, but I figured it would be pretty simple.

First version, VERY rough settings, more for me to see if it would work. Also the pla had been sitting out for 2 years so it was perfect for prototypes.


Found out I made a spot WAY too thin! And beefed it up to try it out.


It was way to wobbly and flexible, so I redesigned it a little. Which worked a lot better


Some final tweaks and more printing and I have this, which is far too much fun and probably much too loud(yea right).
It works great with the Tech-T Shaft kit or just the stock 3-Way with the bend cut off(there's a set screw for this purpose).

Hello! I saw on the site that you did a WGP pump modification. Here in Europe it is difficult to get access to such things. very few people use WGP anymore. Could I ask you for the STL file for this? thank you very much! Regards, Kendzsi

Hello!
unfortunately I can't reply to your message, so I'm writing here.
yeah I know! I have one too, so I would like to ask for it.
I saw that this is a pump accessory where I don't have to break the marker into pieces. it is very good. thank you very much for your help!

It's gone through a few changes since.

So how does a pneumatic pump work, looks pretty simple to me

It actuates the 3-way, causing the ram to chamber a ball. Since the trigger is no longer responsible for triggering the 3-way it breaks the semi-auto functionality.
