I used Cura. I heard there is a way to edit the support structure but I didn’t know when I printed it. I also need to look into that. The program doesn’t show the support structure after before printing but I’m sure there is a way to view it. I just need to look into that for future prints. I also didn’t think much about how I oriented my print. Most of the small, including the smallest holes, wouldn’t need support structures if they were positioned vertically. However, my holes where mostly positioned horizontally. I’m using a Monoprice Maker Select printer. The entire print is just PLA. I don’t think it is possible to use a different material for support structures because there is only one extruded nozzle.
