This is a 10" Rack mount for a Lenovo Thinkcentre M625q Tiny with the measurements 180x183x35mm.
Should fit other PCs from Lenove as well.
I used print on supports. I set the brush type to trianlge an painted on the overhangs as seen in the pictures. Should also work with other support type.
The author remixed this model.
I remixed the original mount so that the whole front of the PC is exposed, which I think looks better. Also, I added some stability improvements due to the slightly different design and enlagened the bezel to fit my other rack mounts.
