Lasercut pH pad case with 3D printed buttons After making some pH pad tests I decided to design a case for them tin Rhinoceros to keep them safe, dry and clean. I used 3 5mm pieces of metacrilato or perspex that I have also engraved the top. You can also use a 3mm piece for the top and bottom and a 5mm for the middle one, which is the piece that essentially determines the depth of your case. I extruded the surfaces and rendered them so I can have a digital prototype of the case as well as you can see here below. The 3D printed buttons are like poles that are entering all 3 layers of the case and act like a fastener. On the bottom, the button acts like a stopper so the case has a starting/ending point. I modeled some tiny circles (2) to glue on the bottom and top right side of the case so I can stabilise the left side of it since the buttons have a 1.5 mm base.
