i'm trying to find a DLP3D printer that will be able to print with the precision i need, so i created this to send as a test object. the screw and threads are #0-80 I've had difficulty getting SLA printers to print where precision in all dimensions was a factor. so, if this will print, then whichever printer can print it will work for my needs and probably the needs of others :) its very tinydownload files. upload to printer print files measure cube, it should be 3/8 of an inch in all dimensions. the screw head should be 4mm across the screw should fit into the threads from both sides when there is a gap, the screw should continue into the threads on the other side of the gap. you may be able to print this model with FDM printing if you have a very small extruder but it would have to be well tuned. so far i've had no luck getting SLA printers to successfully print it because of bleed over curing of resin. however high end sla units probably can print it. im hopeful that a DLP setup can print it. if you print it, please let me know what you used.
