Shywatcher StarAdventurer Iluminator from Glow In The Dark Filament

I always tend to forget the iluminator that comes with the tracker at home or when I have it with me it never has battery so I thought why not print one. The one I found already made on the internet was to lose for my tracker so I just measured the original cap and created one with the same dimensions and design in FreeCAD. 

Depending on how your printer works you might need to scale the model to fit just good. With my calibrated printer I did not had to, but the fit is on the ‘to big’ side, it needs some force to put it in and out, so your experience might vary here.

I printed it using 0.2 layer height, 3 perimeters, 3 top and bottom layers. Infill does not really matter as there is very less of it. Also, it does not need supports.
