3D printing!
Some prints are my own design, some of them I've found online. I prefer finding something and tweaking it to suit my need
rather than starting from scratch, it saves alot of time and head ache.
When 3D modelling I use Blender, an open source 3D software, I personally found it easier to use.
I started printing with PLA filament but moved on to ABS after i tried using a PLA printed CPU bracket in a PC I built (see below).
Turns out PLA softens at around 70°C and my first print ended up in the bin. So I built an enclosure for my 3D printer and bought a roll of ABS.
The nice thing about ABS is that you can smooth out any imperfections with an acetone-bath and you get beautiful results as long as you're
careful not to leave it in for too long.
The downside of ABS is that you really need an enclosure for the fumes and to reach a temperature where the filament accually sticks to the build plate.
I use a Ender 3 Pro with a Raspberry Pi running OctoPrint with a connected webcam and a DS18S20 temperature sensor so that i can see what's printing and get
the enclosure temperature in the same webgui as nozzle/bed-temperature.
