I’m having a very large 20+ part project printed by a guy on 3D Hubs, and throughout the process he has gone the extra mile to make sure my parts are of the highest quality. I originally chose him because of the quote price, but through all of his troubleshooting and reprints I know the original quote won’t cover his expenses. He graciously didn’t ask for additional compensation, but I want to gift him something that shows how much I appreciate his hard work. I was thinking of gifting some filament that he would use frequently, in a commonly used color. His printers can print PLA, ABS, and PETG. I believe he primarily uses a Prusa model, but I’m not sure which one. http://ift.tt/2dftB2X
