Larcset Enclosure Project

A customizable enclosure for the larcset QRP kit.  This is an on-going development and changes will happen over time.  Here I’ll keep up to date a list of developments and a link to the project.

Current files are located here.

2026-01-25:  Uploaded current files. This latest update includes:

• studs on the rear panel for mounting a regulator for the DigiVFO and Reverse Polarity.  This is still experimental and not tested for accuracy.
• Version of the enclosure which has a speaker grill on top and a plate to hold the speaker in place.  This is also experimental and we have not printed or tested.

The ZIP file contains:

• Notes on 3D printing – It’s a good idea to read the notes!
• KiCad STL output of the PCB (for reference)
• FreeCad files for the enclosure
• FreeCad files for the Microphone
• STL files for each part:
  • Front Panels:
    • Replicated regular front panel like the one provided in the kit
    • Front Panel with Fine tune control
    • Front Panel with Digi VFO and fine tune.
  • Rear Panel
  • Bottom
  • Latch Pins for the DigiVFO mount
  • Main Enclosure
  • Main Enclosure w/ Speaker
  • Speaker Holder
  • Microphone
    • Microphone Main Body
    • Microphone Strain Relief
    • Microphone Back
    • Microphone switch Plug
• 3mf example files w/ text added – Note these may NOT be up to date.  For reference settings only.

About the FreeCad file

• There are several variations of “body” parts.  3 different front panels.  2 types of main enclosures, with and without speaker.    Show/hide different bodies by selecting the body with a mouse then space bar to toggle.
• Some of the dimensions are in the spreadsheet. For example if you change the board dimensions or maybe the size of a screw hole everything in the project should change which references it.
• Also used is some more advanced topics such as sub-shape binders to reference other bodies.  Being mechanically incompetent it’s far from perfect but works.  It’s a great learning example.
