Thanks for the assembly video! One question: Would it be possible to 3d print the plunger rod, either out of PETG or PLA? I was wondering because I was forced to use an aluminum 3/8 inch ROUND rod, rather than square, because my local Home Depot did not have aluminum 3/8 inch square rod. Since the square rod is more ideal, I just wanted to know if it would be possible to 3d print. Thanks!
It's not something I've tried so I really don't know. Meaker's MK18 uses a printed plunger rod but his a little thicker that the 3/8 square I designed my parts around. It's certainly something you can try, I just wasn't convinced it would be strong enough.
Very nice! I am wondering if you would ever consider selling premade Rainbow pistols. If not, I’m wondering if you could tell me where you purchased the non-3D printed parts. Sorry for the trouble.
Not sure how many more of these things I want to build. It really comes down to material availability and time... and lately I'd rather be working on other projects ;) I purchased the 3/8" aluminium square bar from a local metal supply shop. PVC I bought from a local hardware store. The music wire for the internal magazine spring I bought from a RC/hobby shop(I bought the smallest size wire they had and bent the springs myself). The O-rings, nuts/bolts, and poly carbonate tubes I bought from Amazon.
Actually, I have another question. Do you happen to know approximately long 2 cm of uncompressed k26 is when compressed? I am using a 9 1/2 cm piece of k26, and it is 2 cm shorter than your 11 1/2 cm length. I am trying to figure out where to cut the notch in the priming bar. Any information on this that you could give will be appreciated!
To figure out the size of a spring when it's completely compressed you want to multiply the thickness of the spring's wire by how many coils the spring has. The thickness of the wire in a K26 is 2mm. The number of coils you have in your spring could vary if the spring has "squared off" ends or not. In the case of the Prism you'd want to then add 9mm to your measurement to space the slot back into the "catch block". Your 1cm slot begins at this measurement. So, front the front of the priming bar, the catch slot in the priming bar goes here: (measurement of the compressed spring)+9mm=slot begins here (measurement of the compressed spring)+19mm=slot ends here You may want to space the slot back a couple millimeter to make sure you can get the priming bar to catch before the spring bottoms out.
Amazing!
hi.
Where can I find the bullets.
how should support settings be.
for pla printing

Were do i buy this?
would have been nice if that were to be a mag fed build

Alright, I might try printing one when I have the chance. Anyways, thank you!

@@ehdrien1094 Alright, thank you for the information! I have the slot cut, and I hope that it will work!
