As we know, 3D Printing technology has developed rapidly in the last 1 decade, especially in FDM or Fused Deposition Modeling, which has developed in various fields.

Starting from last year in 2020, COVID-19 has made many changes in various things, especially the economy and business. Since I only have 1 income as a VoIP engineer, I can't depend on just one job.

Then I thought that I used to really want to have a 3D printer, and I bought one, it was Ender 3 Pro

Not having any skills in 3D technology made it take me a long time to start printing my first work. Many of the calibrations and upgrades performed didn't make much difference to the print results.
