FEP punching template for Wanhao Duplicator 7 vat

thingiverse

Either you dislike something, or just want to do it other way, whatever is, if produce good or better results and is simpler to do a task, that's a good reason to go for that. It was also the case with replacing the FEP sheet on a Wanhao Duplicator 7 vat. When I read the instructions it appeared to me you may have to have three hands or something. Moreover, many people complained of failed experiences. So, I though to my mind: it will come to me too! Well, then let's get prepared. The attached template is used to mark on FEP the position of holes that are required to stretch the FEP sheet "drum tight". The position is not exactly the position of holes in vat, but slightly shifted 1 mm away from the center - actually from the symmetry axes; should you want to be more exact, you can do some math and find more accurate positions ;) Use a permanent marker to outline the holes. Make sure some kind of line is still visible on the FEB sheet since it is not so friendly with any liquid, and hence the usage :) After marking use a punching tool, 4 mm diameter, to make the holes in the FEP sheet. Then take each screw, pass it through the frame hole first, then through the corresponding hole in the FEP sheet. Don't mind it does not look nice, it shouldn't... yet. When all screws are in place, put the entire assembly over the bottom of the vat and give each screw one turn into its own hole. Afterwards, just tighten everything as seen in other tutorials. I've taken some pictures and I may prepare some detailed instructions if needed. Note: Should you have questions, please comment in The Black Brother's page on Facebook.
