New prototype version 2.0 of Gateway 3DS traveler, slim and conceived as a module version. You can plug your battery module pack (rechargeable or not battery pack) to it and power it.
Price for my actual prototype is 33.50€ ($37.3) with no plastic box (only assembled module + 2 x AAA case holder with switch), price includes all pieces and assembly work time (I estimate 1 hour for assembly when trained, since it took me 4 hours to do it for the first time with all problem I had to solve in the mechanical).
I can have quantity pricing if I order the pieces to my furnishers to assemble more than 20 modules (a price is also possible for 10 pieces, but lowest price with 20 units or more, any more). Then the price for the same prototype assembled with AAA battery holder is 18.50€ ($20.6).
So I ask to any potential customer to write me an email if you are interested in buying a unit because I won’t order pieces for 20 unit to assemble if there is not at least 20 customer interested. If you want a good price, there must be enough customers. I will give you the information of the lower price possible depending on how many customer wrote me an email for a potential interest in buying (this is only for a potential interest to buy not an order)
A battery lithium ion optional module replacing AAA is possible, for replacement of AAA holder (this lithium ion module has a full security electronic to protect against overcharging, underdischarge, overcurrent limitation, micro-USB connector for charging and LED indicators of charge and discharge, 2000mAh capacity).
There is a plastic box design in progress so that a “in the box, ready to use” version will be available for selling.
I don’t know the exact price for the box (printed with a 3D printer) for now because the exact volume of the box because there is some modifications to the actual model but for now it is estimated to 7€ ($7.80) for the two boxes: both module box and battery box including plastic, micro-sized nuts and bolts (costs as much as the plastic of the box!) and electric use and a little fee for 3DS printer intensive use.
