In case anyone here doesn’t follow it, Ivan’s YouTube channel is awesome, he has been working on a crazy marble clock: https://youtu.be/K3FMVmAte3g

ProperPrinting is also great, he has some cool videos on custom extruders and printers he designed and a wild extruding resin printer with UV lasers.

They sell an official version of this for about $1000
