I designed a parametric model in Fusion360 for magnetically holding parts to the bed of our PNP. It has been built to allow you to specify how many lanes of parts you want, how wide the tape is, etc. From there it builds the body of your part which you can then either print or mill. For those of you who need something like this, or would just like to play around with the part, link is here http://a360.co/23rUlmW and the covers are here http://a360.co/1UriLHc
