oscilloscope chassis

Summary

This is a 100% original, bolt-free sliding enclosure designed from scratch for the popular DIY Simple 500kHz Oscilloscope with STM32 project by Mirko Pavleski (mircemk).

If you want to build the electronics for this scope, you can find the full circuit layout and code here:

I designed this housing to give the project a clean, hardware-free cyberdeck aesthetic. It uses interlocking sliding rails and integrated magnet slots rather than screws or heat-set inserts.

Design Features:

• Slide-Lock Rail System: The front faceplate smoothly glides into integrated tongue-and-groove side tracks on the main chassis body.
• Engineered Clearances: Modeled with a 0.15mm to 0.2mm sliding tolerance and 0.4mm internal fillets, ensuring it prints beautifully on standard FDM printers without jamming.
• Magnetic Latches: Integrated precise pockets on the inside margins for small neodymium magnets/steel washers to keep the enclosure securely locked.
• Weight-Saving Side Grilles: Designed with open side walls optimized for a stylized tri-hexagonal ventilation mesh.

Slicer Hack & Print Settings:

• Orientation: Print the main chassis box sitting flat on its back wall. Print the front and back panels flat on the build plate. No supports are needed!
• Filament/Time Saving Hack: To get the open mesh look on the flat side panels without the massive print-time penalty of CAD-modeled holes, leave the panels solid in your CAD/STL. In your slicer, add a modifier volume over the center mesh area and set Top Layers = 0, Bottom Layers = 1 (for a clean interior floor/magnet slot base), and choose Tri-Hexagonal Infill at 15-20%.
