wall adjustable air vent
Description
This project has been a pain in the neck to produce. Let's call it a challenge :-) ! The excellent original design comes from Hartvik : https://www.thingiverse.com/thing:3195581 I tried (hard) to adapt this beautiful design to my needs : a rounded adjustable air vent instead of the squared original one. But quickly, if the design is not WATER TIGHT (this is the important feature...), then cura ... makes it solid for you ! There's plastic filled everywhere... even where you don't want it ! So i had to pay special attention to make a water tight design. I use the 2017 free version of sketchup. I used the "union" plugin. Because i ve had no success "stealing" from Hartvik design, i used an other strategy. I ve been stealing the screw and nut from Mistertech excellent design : https://www.thingiverse.com/thing:2076034 The result is not perfect. The screw is wobbling. Some more versions to come. In this design i tried to avoid "massive use" of support because i don't like the surface result. Still for the spindle you need to use support. For the infill i used gyroid because i ve read it was the best compromise strength wise. For the bottom and top, i used circular pattern for aesthetic reasons and 4 layers for the tops. (only 2 layers for the bottom). The design consists of 3 parts : 1) the base (about 4 hours) 2) the spindle (about 4 hours) 3) the screw (about 2 minutes) Things to improve : - groove on the base - wobbling on the screw (make it bigger probably) - snap in screw slightly too big
