3D Printing air flow for Ender 3 Extruder

First piece done. I have decided since I updated the firmware on the ender 3 to TH3D to provide thermal runaway protection. The stock Ender 3 does not have this in the firmware. Why? That is a good question. But it does not matter now. I had to first take my arduino and connect it to the 3d printer internally since the Ender printer did not have a boot-loader. So I had to program the arduino to program the boot loader to the board. Once I did that I was able to disconnect the arduino and hook directly to the Ender with the laptop and then load up the TH3D firmware which provides the thermal runaway protection. So lets see if printing the new airflow extruder pieces improves the print.

SO this is time-lapse comes from octoprint which runs on a Raspberry PI that I have connected to the printer. It takes this cheap 3D printer and puts it on the web in my house. I can now use an SSH tunnel into my home to monitor/stop/start print jobs. Octoprint also streams my prints to youtube so I can watch them from anywhere since I don't want to put my 3d printer on the web for the whole world to hack.

This is the first piece which is for the fan that cools the actual hot end. I am now printing the air duct for where the filament comes out the nozzle.

I found this in thingiverse  I had blue already loaded up and pretty new so I printed it in blue. I used cura to slice it.  This took about 12 hours to print. Video is a timelapse from octoprint I run on a Raspberry PI connected to the printer to give my 3d printer a web front end to print from and monitor.




Here is a picture with an air plant in it.

Another set

I've never actually ever have gone back and did a pattern more than once. I promised to make one of these for my wife since I was stack cutting thse at Christmas and I had too many in the pile and I lost a bunch of them when I pushed too hard against the blade. When you do that the blade will curve and when that happens you end up cutting at an angle. For my stack it ment the lower layers where ruined from the flex. So I have done a couple more of these. I was able to stack these as just two and was able to complete the cuts in a signle day. Had a nice warm day here today so it was a good day to cut.

My usual Watco Natural Danish Oil.

I need to figure out what I am doing for the 2019 NC State Fair and get that done earlier then in previous years. Still deciding. I have a bunch of patterns just have to decide.

Tahnks for looking

Chrstmas 2018

Well I made a bunch of these as gifts this year. This is a Sue Mey pattern froim the Family Series this particular pattern is available here: https://www.scrollsawartist.com/family-roots.html

This  was not a diffucult to do. I cut it on 1/8 Baltic Burch for the plaque itself.

I cut the backer out of 1/4" Baltic Birch

Since the backer is too thin to nail I just used 5 minute epoxy to attach the hanger. Also I made the backer slightly smaller so that you don't see it from the front.

I won't post this before Christmas since I still have hve to give these away. So once I have given them away I will actually post this. I for some reason almost forgot to take pictures of this for the blog! I actually had to unwrap one to take them. Now I have to wrap it again.

Anyway I wrote this entry on Christmas Eve and thanks for looking.

Merry Christmas 2018
