5209 keystone holder

I hate having to paste a reed contact that after several times that the put and take out the battery starts to become unstuck, then I drew a holder so as to improve the bonding surface, has a thickness of 1mm, then slips anywhere without creating clutter. The dimensions are small and tight tolerances,If u don't have a very precise printer u need to scale the file + 10% and fixed contact with a bit of glue.If u have a very precise machine you need a 0,2-0,25mm nozzle and a very clean filament. It's all, good job!

PS very important,I forgot to specify that the scale of the object to be x10.
Is an incorrect setting in the conversion of inventor when I export the file in STL. I seek the problem and solve it as soon as possible
