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

thingiverse

This requires 6 x M3 socket cap screws (nuts optional). You'll 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's used as a PCB drill and works great on medium speed settings and feed rates of 10-20 mm/m while drilling FR4 1.6mm PCB with 0.6mm drills in 1/8" shanks, leaving a nice burr-free hole on the bottom side. Bigger drills like 1mm+ can feed at rates of 40-60 mm/m through PCB but will leave burrs to be processed (maybe placing 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 G-code that the printer cannot understand. So, post-processing G-code files is necessary if the i3 can make use of the G-code from Flatcam. I'll be doing a write-up on Instructables about this process and any Python program I write to process the G-code 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 don't have a Patreon account, but if you made one that worked for you, just like it, and maybe leave a comment, thanks!
