FlexATX Tray w/2 drive mount.

thingiverse

This thing was made with Tinkercad. Edit it online at https://www.tinkercad.com/things/exGWOjzG2BT We have arrived at a usable version! Virtual assembly went well, as did my initial printed version. Printable Parts: 4x bottom 4x middle 4x top 3x Tray1 3x Tray2 Unprintable Parts: 7x M3x10 Socket cap screw per tray. Recommended: M3 screw tap. Print Settings Rafts: No Supports: No Resolution: 0.3 Infill: 50 Notes: 50% infill might be overkill, but I wanted the tray parts to be rather rigid. Post-Printing Assembly Use a screw (or tap) and run through all the screw holes before trying to assemble. This will make the screws much easier to install later. Take one pair of Tray 1 and Tray 2. Pre-thread each of the three mounting tabs on Tray 1 with a screw. Sit the tray parts together with the mounting tabs facing one another and screw them together. Repeat for remaining trays. See assembled image for assistance. After assembling the trays attach flexatx_bottom_mount to the 4 corners of the tray as seen in the assembly image. This fit is generally tight and may require slight trimming of the mount. When the screw is installed it may protrude as much as 2mm, a rubber standoff might be desirable or you can simply back the screw out until it does not protrude from the bottom of the mount. (I may revise the mount to correct this at a later date.) How I Designed This I took the ATX design specs from here: http://www.formfactors.org/developer/specs/FlexATXaddn1_0.pdf The drive hole spacing came from here: https://www.hgst.com/sites/default/files/resources/dk23xx_ig.pdf Used this for the switch/led's: http://amzn.com/B00LGKQ1SS And everything else was made up.
