Circle Jig for Router

cults3d

This is fine and useful piece of equipment if someone needs to cut a circle from a wooden plate by using DeWalt DWP611PK (US), D26203 or D26204 (EU) plunge router. Besides the 3D printed parts which you can download their stl files here, some additional hardware is needed for the final assembly. The hardware list is as follows: - 2 ea. steel bar, Diameter = 8mm, Lenght =~50cm (Lenght is upto you) - 2 ea. Steel Bolt + nut, M5, 30mm - 1 ea. Steel Bolt, M8, 50mm - 3 ea. Nut, M8 - 2 ea. Washer for M8 bolt, Outside Dia = 16mm - 2 ea. Ball Bearing 698 (ZZ or not) - 1 ea. Bakelite cast M8 Knob (One can also design and print this knob) - 2 ea. brass pin D = 5mm, L = 8mm (To tighten the steel bars) 3D printed body which is the biggest part, has two M5 threads on top of each steel bar for tightening them. M5 standards has fairly fine threads and 3D printers with .4 nozzle might have difficult times to create these threads especially in the given printing orientation on their plate. In such cases, you can use M5 tap to re-cut these threads. It will be nice improvement to have M5 steel nuts instead of 3D printed threads. First update (if there will be) might handle this issue in coming days. Base circle of the jig has 4 notches. These are for centering the jig on top of the target circle's center. Draw a cross on the center and make the notches aligned to these center lines. You can use double sided tape to fix the jig in place or use clamps for arcs. Max diameter size of the circle to be cut depends upon the length of the steel bars. I used 49cm bars. This orientation can cut maximum ca. 80cm dia circles. If you need larger circles like table tops etc, you need longer 8mm steel bars. I use 0.2 mm layer height and 30% infill. Here in this model I prefer 4 layers for top and bottom, whereas shell numbers for outline and perimeter are all 4. No support is needed in the given orientation and filament is my favorite PET-G again. For the final assembly, I provided a video https://youtu.be/lMjVvI9G5dA which shows detailed process of assembling. I hope this prevents possible confusions. Enjoy :)
