**Note I haven't tested these designs yet, I just upgraded to an aluminum bed after my glass bed shattered and now my stepper took a crap so I'm waiting on a new stepper. But I figured if anyone wanted to try this they can go for it. So here is the run down on my design: https://www.thingiverse.com/thing:2335310 My goal with this was to maximize usable Z height while not sacrificing any X or Y print area. I also wanted to have a clean design that fully utilized the Areo fan setup. In order to do this, I felt I needed to change to a Prusa style X axis. I also tried to incorporate some of the popular upgrades into the design. So, here is a rundown of the design: Prusa style X axis Redesign: For this I took from this , https://www.thingiverse.com/thing:2022223/#files, and I combined it with the counter weight upgrade, https://www.thingiverse.com/thing:2213625. When putting this together I recommend bolting up the motor to the right side part and weighing it with a kitchen scale and then add pennies to the left side until they both weigh the same and then use CA glue to lock the pennies in place. Carriage: With the carriage, there are a lot of considerations to take into account. Maximizing useable Z height while minimizing X and Y losses, Parts cooling, belt tension, wire organization, aesthetics and so on. The Wire Organization: First thing is I made it receive the same chain link wire loom that is used in this chassis, https://www.thingiverse.com/thing:1557214/#files, it’s the same chain chassis and chain link I was using before. Also in the realm of wire organization, I placed a couple of hole in the side of the chassis that you can run a zip tie through so you can neatly organize the wires from the extruder fan, heater and thermistor. Parts Cooling: I ended up incorporating the parts cooling fan into the chassis in an attempt to make everything fit in a nice clean package. Here is a cross section view. Belt Tensioner: I wanted to incorporate a couple of options for belt tension. Many people like the zip tie method which compatible with this but you can also use the designed belt tensioner which uses two bolts to tighten. When printing the chassis, I recommend printing it on its side and placing your own supports as trying to take out the supports where the parts cooling fan duct is would be difficult. I also have a chassis for regular bearings and the quiet bushings. I also provide a file for a X axis leveling tool. I print 2 out and snap them on the X axis rods on opposite ends and do a quick paper level. Well there it is I hope you like it. If you have any suggestions or if you try it let me know your results. I will update with my results as soon as I get back up and running.
