The design for a thing I'm gonna make for myself.
The 3D printed hilt will hold a small microcontroller, a clear acrylic sheet and a black u-channel to hold a neopixel RGB strip. The brass looking flower will cycle RGB modes. I'll mostly have fun turning this into printable parts since the code for this already exists as an example in Arduino.
I've been looking at a number of parts coolers, some that I like and some that I don't. They all have their trade offs. I tried most notably the mini me and the circular fan duct that mounts to the bottom of the stock shroud. But bridging for me remains poor (might be a matter of print settings) and I have occasional warping.
Came across this design with 0 comments and remixes which is usually a red flag. But I like that I can see what I'm printing, and it claims to prevent warping by using hot air from above the build plate for cooling. I'm willing to give this a try before upgrading to a 5015 blower, and was interested to know if anyone tried this before or if there are any obvious drawbacks that I'm overlooking.

Temperature, clogging or wrong retraction value? This is a brand-new roll from Polymaker, printed at 210 degrees.
I'm printing at 0.16mm optimised speed. It's printing smaller and less detailed parts very well, normally.
Edit: I noticed it's only the unsupported overhang parts. I'm using the mini me cooling duct.
I'm trying to dial in my Ender 3 with bl touch, and am specifically focusing on Z-offset. After a ABL sequence I'm homing Z and use my calibration cube to check the reported nozzle height. I know my calibration cube to be 1.985cm tall (slight case of elephant foot) and have z-offset dialed in to the point that the nozzle is rubbing the cube at 1.98 but not at 1.99.
In spite of this, I never get a successful print without baby stepping to anywhere between 0.15 and minus 0.7. This value might even change after switching filament.
Is this normal? Or is there a better way to calibrate? Other than that my prints are coming out really well.
On a sidenote, I'm in the process of setting up Klipper so I may have to relearn a couple of steps later. Any experience with that will be extremely helpful.
I want to set up a web interface for my Ender 3, and found many interesting enclosures online (some more integrated than others). I've found compatibility and remixes for different flavours of Pi, including BTT. Which is easier to use with Klipper/gives better performance?
I already have a BTT main board and touch screen. How often did you find yourself use the display after adding a web interface? Is it worth getting rid of it altogether or do you still use it as a fallback?
