Acrylic (Plexiglas(tm)) is great material for creating enclosures for electronic projects. In this Instructables, I'll illustrate the steps in creating a 2-piece enclosure using laser-cut acrylic and a strip heater to make the bends. In this case, the enclosure is for a cute vacuum-tube headphone amplifier (based on the NP-100V12 by Rogers Gomez--see http://diyaudioprojects.com/Solid/12AU7-IRF510-LM317-Headamp/
). But any time you want a nice, simple enclosure (optionally, transparent), this technique can be useful.
What you'll need:
Acrylic: Polycarbonate ("Lexan") won't cut on the laser. 1/8" thick (often 3mm, around 0.118") works well. Thicker will be more difficult to bend. Fluorescent or smoke colors can add a nice touch--I got this fluorescent blue from Inventables.com: https://www.inventables.com/technologies/fluorescent-blue-acrylic-sheet
Precise measurements of locations and diameters of knobs, jacks, ventilation holes, circuit board mounting holes, etc.
Form for bending (more later)
(If you live near Ann Arbor, MI, you'll find these tools and more at Maker Works
, a makerspace. Many makerspaces will have a strip heater if they have a laser cutter.)
