I didn't remember where I saw the original until I ran across this yesterday. I took the idea and added some functionality (I have been working on this for a while). [email protected] ‘s model was the original idea that I built on, but I ended up doing a complete redesign in F360. I could not find the plunger handle, so I added khattoum’s file to the plunger assembly.
The screw terminals work; screws are functional and hold the top to the bottom part; and most importantly, the plunger actually rotates and plunges. It is not quite the same as an actual 10 CAP Blasting Machine, but close enough.
You will need to glue a couple of the pieces together and a spring is needed to make the plunger work. I printed everything at .1mm to aid in finishing later and used supports where necessary.
I have not finished as nicely as khattoum, will have to work on that…
The author remixed this model.
