I have been busy doing the printing of the prototype electrical bulk head cover as well, and also I have worked out how the seat unit will be held down at the front. the first shot is the 3d design, second shot is the prototype print and in place on the bike, the 3 grooves are to carry on running the battery cables down to the bulkhead. This material I printed with is a thermo plastic urethane, so its like a hard rubber with some shock absorption in it, the seat unit fastens onto this under the seat cushion, then I will design/draw print the bottom half which has frame cut outs on each side, to bolt into the top piece keeping everything clamped on to the frame... hope that makes sense , if not now it will make sense when I show the finished prototype. In the last photo, I cut some foam to represent the depth of the electrics , and then drew up a cover that will go over the top of this to keep everything hidden, safe and dry. I only print things on weekends and at nights if the printer is idle, but lately its been running 60 hours non stop with a 29 hour print and a 31 hour print, so I cant get finish that work just yet, and that helps, because sometimes taking a break of doing bike prints lets me see things that I didnt see previously which means designs change, and i dont waste material or hours or effort printing something that would quickly become obsolete. I plan on getting the rear sets on this weekend and draw up the ignition box holder that will bolt onto the back of the electrical bulkhead with the same fasteners as the regulator... thats the plan anyway.. lest see if that works. House of D'art ( thanks again Bevellman for the contact) have made the chain guard which is on its way... fast turn around, great price, and easy to deal with... what more can you ask for
