Everyone hates cannibalizing the already low supply of VB carts for their precious edge connectors, but I watched a youtube video and there is a solution.
Its only $7.99 shipped for 10 edge connectors that dont need to be sacrificed from a edge connector of a real VB cart.
Now all we would need is a VB cartridge case.
And thats where 3D printing comes in, but the results are not perfect, not really close to a molded cart case finish quality, but it works, I printed a red front and back with inset lettering for my Bound High cart, it looks quite good holds the pcb and connector and fits the VB head unit fine, link to post: http://www.planetvb.com/modules/newbb/viewtopic.php?post_id=18147#forumpost18147
Also the cost is a little on the high side just for cart cases (cost me for front & rear & UPS carriage $45) but then they can be made ‘special’ with logos & writing etc.
