Dremel Flex shaft extension Wan Hao/Power Spec i3 Duplicator mount

thingiverse

This uses 6x M3 socket cap screws (nuts optional). You will need to drill from the inside 1 or 2 holes to stick something like an Allen key to lock the shaft while changing bits. It is used as a PCB drill and works great on med speed setting and feed rate of 10-20 mm/m while drilling FR4 1.6mm PCB with 0.6mm drill in 1/8" shank, leaves a nice burr-free hole on bottom side :) Bigger drills like 1mm+ can feed around 40-60 mm/m through PCB but will leave burrs to be processed. (maybe a piece of thin MDF under the PCB to prevent burrs? Processing GERBER files in flatcam is not ideal for the i3 because it inserts gcode that the printer cannot understand. so post-processing the gcode files is a necessity if the i3 can make use of the gcode from Flatcam. I will be doing a write-up on Instructables about this process and any python program I write to process the gcode files from FlatCam (which could maybe be used with output from Inkscape as gerbers so flatcam can process them and you can use your 3D printer as a light duty CNC router or even laser cutter/engraver! I dont have a patreon, but if you made one and it worked for you, just like it and maybe leave a comment, Thanks! https://youtu.be/IxYSYMwc9rU https://youtu.be/eRo7yQSXF4Y
