Some of you may remember that I requested a parametric openscad mendelmax-inspired printer a while back…
I could not find a good code base, so I made it myself 
At last; here is the the new printer up and running!
I wanted to fully explore the traditional cartesian mendel design before moving on to fancier motion mechanics, and I’m quite happy that I did.
The code is extremely parametric, my instance of it is using 12mm rods for Y/Z and 10mm for X, with IGUS RJ4JP bearings (ultra-silent).
New lightweight extruder design works great (using 70gr thin/pancake stepper and 13/60 metal gears).
It’s ~300 grams total, which is 1/2 of what my old carriage weighed!
The extruder fans are currently by far the noisiest components (using TMC2100/SilentStepStick stepper drivers), need to switch to 40mm fan on the hotend and a blower fan as layer fan to reduce noise.
