I've been thinking about this for a few weeks, a weekly thread where you get to show off a model of yours around a certain theme.

Let's start with models that you thought would do better than they have so far, they need to have been up on MakerWorld for more than a month!!

I'll start, this is an external spool holder that I designed to replace the type that have the spool edges roll on bearings. I had been using one but a roll of Polychroma had a damaged cardboard spool and just wouldn't rotate freely and kept jamming and causing the print to fail.

Walked by Rockers this evening and it looks like it has closed down! Does anyone know if it's permanent or if it's going through a refurbishment?

With UniQlo opening later this year it got me thinking that these are some of the shops and restaurants I'd like to see come to Cambridge.

Costco

IKEA

Lego

Miller and Carter

The Botanist

Gregg's in the city centre!

Are there any you'd like to see?

Hi Everyone, I am trying to build a display using an ESP32C6 and a 4 digit 7-segement display to show how many total hours my Bambu Lab printer has.

With the "help" of ChatGPT I have come up with the following YAML code, however the issues I am having are:

1/ The display only shows 0 instead of the current reading of 337 2/ In ESPHome in shows as offline and I can't see any logs.

This is my YAML code, I have replaced any sensitive information!

Can anyone offer help to fix this?
