This is my slight modification of the Greg's Wade's Accessible Extruder 5th gen. The reasons for the redesign are a french cleat washer with a finger grip to make it easier to open the guidler door and a post sticking out the front with a slot for a zip tie for gathering and securing all the wiring on your x carriage.
The tilting guildler door screws are sized back to m3 screws and square nuts. The saddle and hotend holes are sized for an E3D V6. The test stl files include test fittings of all the hardware in the same orientation they'll print.
I also recreated the model from the STL in Fusion 360 (here's the model. There are some user parameters that let you change some of the hardware hole sizes (including the hotend holes and saddle) and a few other things. You can also change the offset of the outside hobbed bolt bearing by specifying the distance from the inside of the bolt to where the hobbed groove starts (it assumes a 3mm wide groove) and how thick your washer is.
