Summary

Model stand with light for usb led light with touch switch (as shown on third photo).
a.k.a. Piggy charger ('charging' station for Piggy printed with glowing filament)

Can be used as a lamp. Just use small glass, plastic container or a printed model you like (may be best with round objects with cutted bottom, like christmass tree ball shown on photo).
The more infill/walls the more light will be diffused.

Can be used with or without removable covers.
Covers are for models to put them in best position and/or to diffuse the light.
Use 'Stand_cover_uni-full' or ' Stand_cover_uni_full-diffuse ' to cut the shape of the model inside it on 1-2mm height.
Normal size covers will easily fit and rotate in stand hole. Print it at 101-102% size to hold cover in place. - Stand is with 2 holes on sides on the back to easier remove bigger covers.

USB light is ~3x1,4cm for board and ~4,5x1,4 with usb.
I may change the model a little to fit different usb lights if it will be popular and you will send me dimensions.

Print with symmetrical infill (10-100%).
2-3 walls.
No supports needed.
