Hey everyone, I’ve got it stuck in my head that I’m going to build a Reprap 3D printer after I return from my deployment. My reasoning for this is to help make parts for the 2 simultaneous GB1 pack builds for my wife and myself. Now for the question at hand, who is good at SketchUp? I’m trying to create arcs that doesn’t exceed the width of the base of the arc, and just can’t figure it out.
Does anybody know a way, or perhaps a better (FREE) CAD program that I could be using?
Here’s a pic of the gun body I’ve been working on for 3D printing if I can make it that far. All I need is the hole for the handle in the back.

A RepRap is great in theory but it will take a crazy amount of optimisation to get a print resolution that you’d be happy with. I wouldn’t go into this aiming to use an untested tool to create something you might need within a fixed time-frame.
You might be better asking around local maker labs to see if anyone can demo a printer for you and describe the shortcomings and things you should consider before deciding on a printer.
Agreed.
If I am anything of an example. A RepRap, Makerbot, and Cubify Cube are not going to be able to print a good Proton Gun.
The problem with amateur 3D printers is that there is a handful of things that they make really well and, consequently, there’s an expectation that they can make pretty much anything to the same quality.
I’m increasingly seeing them as a great idea for a group of enthusiastic people to tinker with rather than a personal item that everyone needs. I helped fund an Ultimaker for a local maker lab, spreads the risk and I still get the opportunity to experiment with it.
I’m automatically assuming that the 3d printers will be unable to print that 90 degree bend area just under where the Clippard valve goes. I also figure that it will be rough, and will need sanding.
Also, I just really want to build a printer, and to the best of my research, Little Rock has no maker labs, which makes me a very sad panda.
Hey AJ, I’m about to be sent off on yet another deployment, but is there any word when there will be more sound cards made and available?
