Nicely done, turbocad! Must hit like a monster!
Like I said, I had also thought about running a continuous length of copper wire; but it would eliminate the fuse from the circuit (and any option to use one). In the past, when I was thinking about a similar configuration, I had resisted the urge to employ it, as I felt it important that my mod be configured the same as those I send out to folks. This allows me to try options and modifications that everyone can employ, and to continue to put track time on the standard design. Nonetheless, it makes me very happy to see you playing, improving and reaping the rewards of a top-notch tinkerer at work!
I wanted to remind those who are still looking at all this speculatively (who don't have one yet), that the mod does come with an optional set screw for the bottom cap. This does a number of things. One being that of making the bottom centerpost contact, for all intents and purposes, solid. If one is a button masher, or wants to feel that that contact is always firmly seated (whatever the reason), just employ the set screw and those two parts are jammed together tight. (I noticed a blob of superglue in your magnet hole, in the pics of your modifications T-cad. This, I imagine, played a role in reopening this issue.)
The set screw also goes a long way to protecting the lip under the squonk hole. With the cap locked laterally by the inset magnets and then firmly screwed onto the bottom of the mod, it is very unlikely that any fall would damage that lip. If one is prone to such accidents or is taking the mod out on an adventure, they may consider using the set screw to protect the mod in this way.
In my thinking, the top connection at the centerpost needs no more complicated treatment than a .... joint; as the action of firing (pressing down on the button) only serves to compress that point of contact, and never to lessen it.
The last thing I want to do is discourage anyone from tweaking, altering or souping up their OliveR. I'm all for that. And I do love the stuff that T-cad is doing. Very cool! Also, tho too, I wanted to clarify that the original design of the mod already takes many of these factors into account. I've certainly made compromises in order to provide something that suits almost everyone more than sufficiently (but not every single person ideally); and yet, that's a key element in design, methinks.
