    3D Printing ● ● ● ● ● ● To begin this project, start by downloading the files from Thingiverse: Link Open the 3D models in your slicer(Cura, Sli3er, Simplify 3D, etc.) I recommend using Cura as I have heard that people have had issues with some of the models using Sli3er Note: I also printed one more part that was not listed in the original thing. This part is to help the GT2 belt from slipping off the 624zz bearings. Link Input the settings that you will be using on the parts ○ ○ ○ ○ I used 100% infill on all the parts (An infill of 40 - 100% will work as well) Printed all the parts with 0.15mm layer height Printed with Hatchbox Red PLA Link Use supports on the Penholder, Slider, X_Support_L and the X_Support_R (Remove the supports from these parts once they are printed) The longest part took around 9hrs and the shortest took 30 minutes to print
    Cut your Linear Rods to Length ● ● ● ● If you purchased rods that were cut to length, then skip this step Use a measuring tape and sharpie to mark the spots where the rods need to be cut ○ ○ ○ Use a vise to hold the rods in place when you cut them Remember that you need (2) 350mm and (2) 450mm long linear rods On the threaded rod, mark your cutting point at 470mm I used an angle grinder to cut the rods Then I took a bench grinder to smooth the ends that were cut
    AssembletheX-Axis(Linear/ThreadedRods) ● ● Take the (2) 450mm linear rods and insert them into either x-support part ○ ○ Use may need to use a round file to smooth out the holes that you insert them in Also, you can use a rubber mallet to help insert the rods Now take the threaded rod and insert it in the hole below. Feed a 5/16in washer and 5/16in nut on both sides of the x-support part
