Hi John, well as Geoff has probably already let you know, I sent him a selection of 5 lens caps I bought off ebay which cut beautifully. I then bought 100 from China and had them sent over, I sent them to Geoff and when he tried to cut them they melted, indicating a different plastic. Do you think your laser would be able to cut them? I need to have 100 cut for my personal project, and am willing to pay. Unfortunately I missed the opportunity with working with Geoff because of these new circumstances but as everyone on here probably already knows he's a top bloke :)
