Attic Hatch Latch

Latch for a drop down ladder that un-collapses when it comes down from your attic. The latch actually goes on the door that is actually an access panel to the collapsing ladder. These types of latches are made of plastic and commonly break. So why not 3D print yourself one with a better / stronger plastic such as Nylon or plastic with carbon fibers in it. Version 2. The first version was too exacting, this version is a little bit more forgiving in several dimensions. Changed the Hook height gap from 3mm to 6mm. Change the slope to the Top from 12.5mm to 17mm. Changed Hook length from 7mm to 9mm. Added hole between top and bottom for the spring. Added a 10mm fillet on the slope Top. Added a bunch of 1mm fillets.
