Other Tweaks and Upgrades

There are a variety of things, mostly minor, that I've done:

• More Filament - I now have: Red, Silver, Blue, Black, Gold, Forrest Green, White, Orange and Teal in PLA. I have Black and Orange in PETG. I have a bright green in TPU. The Red, Orange, and Teal PLA is PolyMaker's PolyLite. The red was actually my second spool of filament and I found that I really liked it. It seemed to be a better quality than either the Hatchbox or Matterhackers filament that make up the rest. I also bought a spool of cheap filament (~$14) in a lackluster orange - it was terrible stuff and clogged up my nozzle. I'm NOT going to use it again. I may try it with the 0.8 nozzle.
• More Nozzles - When I printed the Pi Cup in vase mode I found that the walls were pretty thin. There has also been a time or two I wished for a finer nozzle to print something extra fine. So I ordered a set from eBay titled '19Pcs MK8 Extruder Nozzle 0.2~1.0mm For Makerbot CR-10 Ender 3D Printer M6 Set'. Well, they are NOT the proper nozzle for the Ender 3 (or the CR-10) so I ended up 'returning' them. The seller first tried to make me pay to ship them back (since the shipping was free the return must also be free) and then offered $1 if I would forget it. I said 'No, you misrepresented the product. I expect a refund.' I finally got the refund of $3.53.
  
  I ordered from a more reputable source that described things better and got 10 nozzles for a little over $9. They are the correct nozzles. I'll get around to trying them sometime.
• Spool Holder Upgrade - I printed a spool holder that uses 608 bearings so that things roll smoothly. It uses 3 bearings but I only had 2 so I ordered more. It still works with 2. I used this one: https://www.thingiverse.com/thing:3502973
• Remote Power Off - I'm working on a remote power off system that I can trigger from OctoPrint. I don't see any need for remote power ON. If I'm not here I do NOT want to turn on the printer. I've got all of the parts now. I just need to put it together.
• Reprint the Extruder Knob - The PLA printed extruder knob just didn't hold up. The shaft flat (or key) just rounded itself out and the knob became useless. So, once I got the orange PETG I decided I needed to print another knob with that. It is holding up nicely and I actually use it to feed filament. No more holding the lever and pushing filament in. It also works great for extracting filament most of the way out.
