Itty Bitty Double Extruder

'TechMasterJoe' thanks for the model. Nice.

'lemming' it printed really well for me too. 'clough42' designed it to print without support. Mine came out really well and I don't remember that I had to drill out the bottom. What I did find though was that the inside of the filament path was not very smooth. I took a 1 foot piece of all-thread (1//8") and ran it up and down the channels to polish them out. I went back and forth a lot until the threads had cut a nice smooth channel. I've had no problems printing.

What is it? The picture is too small for me to see it clearly.

It's a deburring tool. Sometimes also called an edge breaker.

Got my deburring tool today. It's really nice and is so much better than the back side of an xacto.

Thanks for the tips

I cleaned out that area by scraping a large flat end screwdriver in their and now it's pretty flat.

When I cleaned out the filament hole, I ended up putting a little bevel on it. I hope it won't negatively affect it.

The filament moves pretty freely through both holes with just a small amount of resistance. Is that fine, or do I need to touch it up with something?

BTW. Given that I'm about to go to the time and expense of implementing dual extrusion, is their any benefit of changing over from 1.75mm to 3mm filament?

Great community - appreciate all of the help

The red handle thing is as I call it a whirlegig deburr tool. It will shave time off your tasks so you can spend time with the misses. Lol.
