00:00In this video you learn how to convert threaded CAD models into a working 3D print.
00:08Here you see the threaded bottle model which was designed in FreeCAD 1.1.
00:13To export it to an STL file for 3D printing, select both bodies with the control key.
00:19Then go to File, select Export and save it as an STL file.
00:23Do the same with the threaded CAD model.
00:28Load the bottle model in the slicer.
00:34Click on the scale button and scale it down to 50%.
00:41Leave the quality at a 0.20mm layer height and click on Preview.
00:50You see there are holes around the thread, so the model has to be changed a little.
00:58In FreeCAD, open the sketch where the circular cut is.
01:02Then change the diameter of the circle and make it smaller, so more material will be left.
01:10Export the whole model again to an STL file.
01:18In the slicer, click on Objects.
01:21Right click on the STL model and select Reload from disk.
01:26And you see the model was updated.
01:28Preview the model again and you'll see it looks good now.
01:35Let's export the G-code for printing.
01:37The bottle was printed in transparent PLA.
01:42So, let's park the Π·Π°ΠΊΠΎΠ½.
02:06For more information, click on the on-campus file.
02:06If you liked it, click on the video.
02:08Click on the icon, click on the icon, click on the icon.
02:10Use the Auto Orient button to rotate the model into the correct position, then scale the model to 50%, the
02:17same as the bottle model.
02:18Click on Preview.
02:21Everything looks right.
02:24Now export it for printing.
02:26Let's push the threads together.
02:28The thread of the cap is too tight.
02:41To fix this, double click on the threaded hole in FreeCAD.
02:46And check the Custom Clearance box.
02:53Enter a clearance of 1.2mm to make the thread wider.
03:00Click on OK to make it wider.
03:04Now export the model and overwrite the existing STL file.
03:11In the slicer, click on Objects.
03:14Right click on the model and select Reload from disk.
03:18You see the thread became wider.
03:20Preview the model and export it for printing.
03:23Please subscribe if you like it, thanks.
03:28And now the cap fits very well.
03:31So this is how you can export and handle two threaded models that need to fit together.
03:50The cap was printed with a print profile of 0.12mm to improve the thread quality.
04:00The bottle thread is a bit rougher, but it's good enough to make the cap fit.
04:04And when there's a bottle, there's water.
04:06Just for fun.
04:09Let's put the cap on the bottle and turn it upside down.
04:26As expected, it will leak a bit.
