Hi. In previous video DIY money making machine part 1 I showed you how to perform a money printing trick. In this one, as I promised, I will show you how to draw the device in free design tool FreeCAD. Coming up!
See the video about it on YouTube.
Well, let’s start designing. All the STL files we will create today will be available on Thingiverse.com. I removed files from my homepage to keep just one copy, which is up to date. See the links in the description below.
Create new empty document. Go to PART DESIGN section. Create new sketch. XY plane, click OK. First we have to design the pipe. We will draw two circles. Constrain each one to zero coordinate. Set inner radius. Enter 8mm. Set outer radius. Enter 10mm. We have a fully constrained sketch. Close design. We will make 3rd dimension with PAD tool. Length will be 12cm. That’s it. Save project and export the STL file. My file is named MoneyMaker1.stl. Remember to print two of these tubes.
Secondly we will create small ring that will fit our pipe. Again the same story. Create new empty document. Go to PART DESIGN section. Create new sketch. XY plane, click OK. We will draw two circles. Constrain each one to zero coordinate. Set inner radius. Enter 10.2mm. It is a bit larger then the outer diameter we used for the tube. Set outer radius. Enter 11.2mm. We have a fully constrained sketch. Close design. We will make 3rd dimension with PAD tool. Length will be 2mm. That’s it. Save project and export the STL file. My file is named MoneyMaker2.stl. Remember to print four of these circles. We will put 2 around each tube.
Thirdly we will create the pipe enclosure. Again create new empty document. Go to PART DESIGN section. Create new sketch. XY plane, click OK. Draw two circles and a rectangle around them. Constrain the circles to Y axis by setting 0mm offset. Set the radius to 10.2mm, so the pipes would fit nicely. Set the X axis offset to 12mm from the zero coordinate. We will constrain the rectangle. Width will be 60mm and the height 30mm. We will define offsets from the zero coordinate. We have a fully constrained sketch. Close design. We will make 3rd dimension with PAD tool. Length will be 4mm.
Now click one of the surfaces. Select create a new sketch. By using going this way, we have our new sketch aligned with the selected surface. We will draw two rectangles on each side. Width will be 4mm as before. Height will be 30mm as before. We will define the offset. It is best to choose outer point as we already know its position. 30mm left and right and 15mm up and down. We have a fully constrained sketch. Close design. We will make 3rd dimension with PAD tool. Length will be 85mm.
Now all we have to do is to draw the same sketch with pipe holes as before or we can just copy it. Click once on the first sketch to select it. We can toggle view by pressing SPACE key to check if it is the right one. It is. Go to EDIT, COPY or press CTRL+C and then again EDIT, but now PASTE or CTRL+V. We got new sketch below named Sketch002. Now we select our last PAD, toggle view with SPACE key, turn the object with SHIFT+RIGHT mouse button and move it around. We select the surface by clicking it once. It changes color. Now go to MAP a sketch to face and select the sketch we have pasted before. Sketch002. It is aligned. We only have to use PAD tool. Again we choose 4mm. That’s it! Design is finished. Save project and export the STL file. My file is named MoneyMaker3.stl. Print only one.
