V3.1 Release

And…we are back! The beta for V3 is wrapping up. We now have a V3.1.

I want to thank Rossum, Kataphratos, BobC, Tim, Alexander Mundy, 4Nic8 and ValHeli for taking on the project and providing great feedback and insight. (Big thanks to Rossum for hosting the beta forum!)

The group came up with a number of good improvements to tweak the design, reduce parts, simplify the build and lower the overall build cost.

V3.1 uses the same external shell parts as V3.0 but has changes to the internal structure. I went to mini “deans” type connectors and changed the battery contact. The top cap is now secured by the mini-connectors and larger magnets provide a nice auto-aligning grab/snap and seats the connectors into place. There is also now an option to use a standard ball tact switch instead of the Alps Mini Tact switch for the fire button. The Alps provides a quieter clicking sound, the standard ball tact has a bit more feedback.

So here is V3.1 update:

This is the raw untouched parts from Shapeways. I only press fit the mini connectors and the older ring style magnets into place. In the dry run assembly, the top of the main structure sat a little proud, but during final assembly it tightens up and can be sanded lightly for a custom fit.

This was fun; glad to answer any questions, I am sure the beta guys would do the same.
