    i am new by about 2 months now using freecad.19. Have learned a ton from dr vax for a 64 year old but am having a brain blockage trying to make a simple round spray can holder 110mm at the back and 70mm at the front and pocket or hole 68mm!! help please

    Sorry, in your post in the other forum I forgot to recommend you post a screen capture of your efforts to date, as well as a photo of the spray can.

      This might be an interesting idea for a video topic. How do you anticipate this working? Are you trying to design a trigger that presses the button on the top of the can? That mighty require modeling multiple parts and connecting them with a bolt. One problem with doing a trigger is you do not want to violate any patents so looking at existing products is a problem.

        Doing a patent search isn't that hard and it can be really interesting. I went through all that a few years ago.

          That's 1 of the many, many problems with the current patent system. I believe the rule used to be that you could make a patented item as long as it was only for your own use and there was no profit involved. We need to get back to that.

              Ok. I get it. You just want a wall mount.

                Here is a FreeCAD .19 model you can use as a starting point. The model is not properly constrained, and it is not parameterized, so do not use it as a sample of a professionally modeled solution. It should, however, give you an idea about how to combined sketches and use data planes to build models. I used the data plane to add the screw holes.

                If I have some time, I will turn this into a video.

                I used random dimensions, so you should click on each of the sketches one by one and put in the proper dimensions for your paint can. I also left the backplate a bit too large, and I would recommend making it just large enough to get to the screw holes with a screwdriver.

                I included a photo so everyone can see what this looks like, and since it has no overhangs, it should print easily on any 3d printer. I have also attached the FreeCAD file.

                Let me know if this is helpful. Irv (Yes, I know only older people sign forum posts, but I am over 65, so I can do whatever I want )

                  Irv Shapiro, trying to find the signature. Did you use invisible ink??

                        Here is a video demonstrating how to produce a model for a problem like this. There are always multiple ways to solve any problems in a sophisticated program like FreeCAD this is just one approach. The key to succeeding in 3d CAD Modeling is to understand that you build up your model component by component. That is why I often start people in TinkerCAD so they learn this concept.

                        Hope you enjoy the video. I used a different editing style to try and reduce my editing time for hands-on software tutorials. Let me know what you think?

                            Ah. I didn't recognize that as a signature. Thx.

                                Sounds like you have defined a challenge for yourself. Let me give you a hint. You can create the tube with a revolve instead of a pad -- a very different approach but would allow you to create a more complex shape. You could also use another sketch on a datum plane that is on an angle to cut an angle.
