Vacuum forming terminal covers

So, when you order from China, sometimes you do not get what you need.  When we originally ordered our Thundersky cells from the distributor, we did not get studs, washers or terminal covers.  After several failed attempts to contact the distributor, we finally decided to take matters in our own hands and make our own covers.
  This year, the EV Challenge officials have required that each cell in a battery pack must be covered.  A single cover over all batteries/cells will not suffice any longer....thus the need for cell terminal covers. A couple of students took it upon themselves to surprise me one day with their creation of a DIY vacuum forming machine.  Crude but effective, they are in the process of forming the needed 48 covers for our lithium cells.  We are using .62 thick thermoplastic from Professional Plastics, a vacuum form box made from 2x4's and a shop vac.  Works like a champ!
