Lack enclosure PSU cooling chimney

<p>I designed this passive cooling Lack enclosure PSU chimney to have a solution not to unmount the PSU from my i3 mk3. the chimney is bolted down to the base plate. you have to cut the side panel twice in width. one part is about 80mm, the other is 267mm. it depends a little on your printers position on the base plate. because of its size of 440mm the chimney can be printed in three segments with support material. it has to be glued together after printing. a one piece version is also available.</p><p>this design works with my silver psu version. others were not tested. but you can tweak the attached openscad file for your needs.</p><p>additional material:</p><ul><li>super glue (mid)</li><li>4 self tapping screws 2.8x9.5</li></ul><p> </p><p>have fun!</p>
