<p>How many times did your printing end and you completely forgot about it?</p><p>Now with the new and only Adjustable Hourglass never a minute goes by without your printer being unoccupied.</p><p>Simply regulate the time according to how long your print lasts and voila.</p><p>&nbsp;You can go anywhere with your hourglass and know exactly when your print ends.</p><p>So: Just print one of each. I recommend printing the entire adjustable mechanism with 100% infill.</p><p>You can print the covers with 20%.</p><p>And the most important thing is to print the body (the transparent part) in vase mode. I used pla and got good results.&nbsp;</p><p>Print the transparent top normally with 100% infill.</p><p>I printed it using a 0.6 nozzle, but simply because it is the one I have placed. You can print it with any nozzle without problem.</p><p>I used a 0.4 layer height (for 0.6 nozzle). So with a layer height of 0.2 or 0.25 it will be more than enough with a nozzle of 0.4 and you will get excellent results.</p><p>You need some super glue to attach the inner mechanism.</p><p>Begin by passing shaft through transparent top.</p><p>Then the "governor lock" piece first through the shaft. Then glue the shaft to the "regulator disk". Be careful with the glue! Then glue the "regulator lock" to the regulator. It should look like a sandwich with the disc spinning freely inside. It has a small notch to help you know the correct position.</p><p>Add sugar or salt to the hourglass and then carefully stick the regulator base into the regulator. I recommend not hitting if you are unsure of where to go. Double check and then glue.</p><p>Then just close everything. Glue the caps.</p><p>And adjust your hourglass with the rotating disk.</p><p>Set the timer (big nozzle dial) and then print!</p><p>Added some videos and photos to help you assemble.&nbsp;</p><p>Unfortunately I forgot to take pictures of the finished model and gave it to a friend, who is now sick with Covid. So I don't really want to bother him now. When we can meet again I will take more photos and record videos!</p><p>I hope to see photos of your prints soon!</p>
