Halogen floodlight SMT reflow

This project was waiting on a box fot two years, until I had to solder 100 PCBs. After some research on SMD/SMT reflow oven hacking, I was confident to build my own reflow device with an halogen floodlight.

Valentia Case-Rap foldable 3D printer

In the summer of 2016, browsing in Thingiverse I came across the Case-Rap 1.0 foldable 3D printer by jlguils. I liked the design strategy of dividing the structure in parts that, when folded, transformed themselves into a portable case. And started to develop my own custom version: the Valentia Case-Rap foldable 3D printer.

Mysterious z ribbing with PLA... solved!

I've been having consistent z ribbing on different custom printers since a year or so...
No matter what I've tried (z wobble isolator, z axis strabilizer, threaded rod diameter/pitch changed, etc.).
Yesterday my heated bed's MOSFET failed while printing yet another calibration cube and guess what... NO Z RIBBING!!!
