I turned one of my workbenches into a printer cabinet for my filament printers.  I later added a resin printer.  Since everything is in my unheated garage, I needed a way to keep the resin warm.  I added a heater and thermostat but wanted to get a better seal around the doors so I added weatherstripping.  The doors then needed some additional pressure to compress the weatherstripping and make a really good seal.  I designed this handle with an angled bottom to apply pressure against the doors once twisted into place.  I used a 1.5" long trim head deck screw and a couple of washers for the handle and 2 0.75" long #6 screws for the ramps that attach to the doors (I designed the ramps for 2 screws each but am unsure whether I will install the extra screws since it works great with only 1 screw each).

Everything is parametric in case you want to change something.
