I use a small UV penlight for spot curing resin when making repairs to models. To keep it from rolling off the work table, I printed this small stand.
I'm including the FreeCAD file and the STEP file for anyone who wants to modify this to fit their needs. Resizing is easy enough within the slicer, but all the dimensions are parameterized using the spreadsheet within the FreeCAD file.
Printed in Hatchbox Blue PLA at 0.2 mm layer heights with no supports. I did have to do some cleanup with a deburring tool, but it works pretty well.
