Locks the window in place when I need a little bit of ventilation when printing :-) Very big thanks to the model maker as I used the combined model to actually get it to print with that placement. My first resin printer and my firsts attempt made me place all the different parts on the build plate, just as I would do with my other 3d-printer, but they lost their grip and did not print completely and got stuck in the vap(?). Much better to just have them floating in air with help and everything went fine. Now I just need to figure out how to upload the Timelapse movie :-) Sliced with the program called Halot Box, uploaded to the Creality cloud and started from my mobile.
