Remix of Complaint Button by GeoDave

Last crawled date: 3 years ago

I really liked this design, but the tolerances were a little tight for my printer. I started to just redo the axles & pins, but then got a little carried away and changed all but the button. I changed the 8mm axles to be an 8mm bolt with 6mm threads on the end. By doing this, I did have to cut an access slot for the hole where the woodpecker gear connects. This is not noticeable when the top is attached to the bottom. Since I had to change the top, I decided to round the corners as well & they are customizable in the openscad script. I used a radius of 20mm for the corners, but up to 28mm should work. Do not use less than 2mm for the radius as I did not allow for sharp corners in the code. I generally had a tolerance of .4mm for axles, holes & threaded parts.
The threaded parts I used a non-standard threading for better printing at .2mm layer height, by changing the thread pitch from 1.0 to 1.25 & Thread_Angle = 40. To modify any of the openscad files that use the threading, you will need to download the threads.scad file from http://dkprojects.net/openscad-threads/
There are 2 versions of the base, one with cutouts for the sign(Base_Mod_WithCutouts_Rev5.stl) I am using & one without cutouts(Base_Mod_Rev5.stl).
You should be able to print 1 each of the parts, except print 2 each of the Complaints_Blank.stl & Complaints_Text.stl.
The AxleShort_WithNut_Rev5.stl are 2 axles with nuts to connect to the woodpecker gear & small gear.
The AxleLong_WithNut_Rev7.stl goes in middle of the springs. I print 2 of these for longer printing per layer, but you only need 1 of these.
The PinLong_WithNut_Rev7.stl goes at the end of the spring connection.
The ComplaintScrews_WithNuts_Rev3.stl are the screws & nuts to connect the Complaint Text.
Follow the directions from the original design: https://www.thingiverse.com/thing:2882432 for installing this.
The STL files I generated worked for me with any sanding, but think I do need to sand the top and bottom of the woodpecker gear for smoother movement.
I used .2mm layer height for all prints except for the Top & Base I used variable layer height with the Slic3r Prusa Edition 1.40.0-beta. This saves probably 30 minutes on each of those prints.
For the top I used these layer ranges
//Top Variable Slicing Layers
//0 - 2.35 .2
//2.35 - 6.75 .3
//6.75 - 26.15 .2
//26.15 - 40.95 .3
//40.95 - 58.35 .2
If you use the base without the cutouts, you could use .3mm for all the layers
//Base Variable layer slicing
//0 - 24.75 .3
//24.75 - 62.55 .2
//62.55 - 77.95 .3
The openscad file for the Spring_Left_Mod_Rev2.scad is also used to generate the Right spring. It is just mirrored about one of the axis.
I would like to change the text a little better, but that works for now.
If I missed something let me know.
