While poking around on the web this morning I found a site that seems to have free STL files for down load and in the spirit of the forum I thought i would share.
I have downloaded a couple and am about to tinker with them hut I am not sure yet if they will work or not.
It actually Hungarian, and you can see some of mine and Jeff’s (picengravertoo posting as jjwmachineco) early laser engraving work on the English section of the forum. http://hobbycncart.com/forum/63-151-1
