Simple Adjustable Perfect Desktop Fan Stand (print-in-place)

I have already made a Simple Fan Stand and an Adjustable Fan Stand.

I showed both types to a friend and he challenged me to do a model that is simple and adjustable and is also print-in-place. I never designed anything which is print-in-place before.

Naturally I was like:

So, here it is!

Design

First I had to design a print-in-place hinge for printing in upright position. (You will need this too if you plan on modifying the design or fine-tune stuff in OpenSCAD)

Then was the geometry. The support bar is to be clicked into the foot at different angles.

I could have done simple grooves as resting places every 5mm or something like this. Instead I I wrote some OpenSCAD code to put a groove in the exact spots to get the different angles in 5 degree steps. I even goes beyond 90 degrees. However, if you intend to use this extreme angle, please use something as counterweight at the back of the foot  I could have made the front part of the foot longer but the resulting model would not easily fit on the MINI's print bed. Oh and the opening for the support bar to click in faces exactly in the direction of the support bar. The support bar has a bend at the end to allow for the lowest two angle positions to stay clear of those in front of then.

Printing

Printing is quite easy, just keep the seams out of the hinges as good as you can or use a bigger h_gap.

Gaps and clearance

Getting the best values for h_gap and v_gap is important. h_gap is the horizontal gap between the axle and the body. It is the difference in diameter so the actual gap on either of the sides is half that value.

There is a Hinge Test in the Hinge model page but  my results show that the rest of the print matters too. What works in the test may not work as well here. 

There is also the clamp value to consider. It is how tight the grooves hold on to the support bar. 0.2mm works well for me but it is on the tight side. you may want to make this bigger if you are having trouble getting the support bar in and out.

I have provided you with a wide variation of the combinations of the parameters that make sense in my opinion. However, you may stimm want to find your optimum by using the customizer in OpenSCAD. As always I have included the small Perl script that generates all the variations.

Be that as it may, the provided 3mf file should work for most printers and shows how to keep the seams out of the hinge where it is possible.
