I have been trying to model a dumpster wheel in Blender, but it turned out to be trickier than I thought. In particular, I just can't figure out how to do the central part (with the holes). I have tried this a couple of times, but ended up with nothing but a mess. Could you show me the correct way to do this? I'm not completely new to Blender, so there's no need to be too specific.

Here's the reference picture:

[And just when I thought I was already past the “beginner stage" in Blender before this. Meaby I should quit Blender and throw my computer out of the window.]

    $\begingroup$ You will always manage to throw computer out of the window because of this problem but I think it will provide you only new problems. You might want to show screenshots of the "mess" you've got when faced problems, although this shape is modeled from hollow cylinder with 2 loopcuts in the middle to extrude inwards the rest shape $\endgroup$ – Mr Zak Aug 5 '17 at 14:24

I’m sure there are many ways to accomplish this. Here’s one possibility.

SHIFT + “A” Add Mesh > Circle with 64 vertices (Top View “7”).

enter image description here

TAB into Edit Mode press “E” and “S” Extrude Scale three times.

enter image description here

Select this vertex and press SHIFT + V and slide it until the corresponding edge is parallel to the X Axis.

enter image description here

Repeat for this vertex until the corresponding edge is parallel to the Y Axis.

enter image description here

Select 3/4 of the vertices and press “X” choose Vertices from the drop down menu to delete them.

enter image description here

Add a Mirror Modifier check off “Y” “Z” (“X” is checked by default). Also add a Subdivision Surface Modifier (Change the View to 2). Tab into Object Mode and select Smooth Shading then Tab back into Edit Mode.

enter image description here

Add two Loop Cuts (CTRL + “R”).

enter image description here

Select the following ten interior faces and press “X” and select Faces from the drop down menu to delete them.

enter image description here

Press “A” to select all and press “E” to extrude them up.

enter image description here

Select the following interior faces and press “X” to delete them.

enter image description here

Check off Clipping in the Mirror Modifier. Select these faces and press “E” to Extrude them up.

enter image description here enter image description here

DE-Select these six faces then press “E” to extrude the remaining faces up again.

enter image description here enter image description here

Tighten up some of the edges with Loop Cuts.

  • $\begingroup$ This was really helpful and easy to follow solution. I also learned a few new things about the Mirror Modifier (like how to remove those ugly seams you get after applying it by removing the interior faces.) $\endgroup$ – Tayskersantti Aug 5 '17 at 20:45
