I purchased a M350 Universal Mini-ITX enclosure to maintain a compact workstation for 3D rendering purposes. As I am tight for space, the situation had to be as little as possible and preferably mount to my 19' widescreen monitor.
The M350 seemed to fit the bill, but it was just after I purchased it that I thought to look at the mounting holes in my screen... Doh, there is more than one VESA standard and my screen and case didn't match.
So I have created as I can make it a adaptor that's as parametric. As well as having variables for the key attributes you might have to alter such as mounting hole dimensions and the height of the adaptor, their are 3 unique styles of plate you can generate using the scad file.
Cross. The mounts are held in place by two crossed beams
Outer Ring. The mounts are included within a ring which has optional oval cut-outs
- Full Strength. (Photos) This has both the outer ring and inner cross members for complete support. I am no engineer, but I am quite sure this is the option of the three.
There is also an option to switch between generating a calibration piece that is much smaller and the mounting plate.
Although designed to mount an ITX case I am sure that this design may be used for different purposes. The total amount of adjustment.
Mine was printed by me in PLA and it appears strong enough to maintain my ITX case and electronics.
Download the file and start in OpenScad.
Change the variable to true to allow the piece to be calibrated by you.
Establish to whatever dimensions you think work best on your printer.
Export the test piece and try printing it. The test piece is 1 corner of the mounting adaptor, you can test fit it that you're going to be using. If you're happy with the test piece place test_piece = false and return to Openscad.
Choose set the options which you want for the adaptor. You can tweak different variables to make the adaptor lighter or stronger. I've tried to comment everything as clearly as you can. If unsure, try changing things a bit and see the effect it has on the adaptor.
You may decide what kind of holes that you would like for 100mm holes that are spaced and the 75mm spaced of each other. There are options for either a trapped nut or a screw and washer. Notice that both variables and the m4_washer_diameter adjusts the size of these mounts so if you're using holes that are nut that is trapped throughout, you will have to play with this variable.
Print with your preferred settings. I printed mine with infill that was 35% and 3 layers. This seems dureable enough.
Insert the nuts and bolts which you wish and attach the devices that you wish to use with the adaptor.
