Bi-color xmas (christmas) tree lamp

Included four stl files are intended to print a "bicolor Christmas-tree lamp" on a single color 3D-printer (in my case Creality Ender3 V3 KE printer; slicer: Creality print).
It's easy to print. Colors are at your choice. Glue is non needed, but you can also glue all parts together.
No need to activate slicer's s.

You can print two versions of the lamp: (main body-1) to be used with internal ikea Kapplake led-lamp; (main body-2) to be used with an internal generic strip-led (I used a RGB strip-led). In any case front-face and rear-face STL is the same.

(1) The internal light of first version of the lamp is designed to be used with an Ikea Kapplake 5volts DC 74 lumen led-lamp. Model is designed to fit it: use doulbe-sided tape to fix it.
(2) If you prefer an internal generic led-strip use second version of main-body STL. I designed internal hooks to fix the strip but you can use double-sided tape instead.

I printed two prototypes to show two versions of the lamp using already open filaments available at my home.

First prototype is printed with external structure in eSun PET-G semi-transparent green filament, internal front face in eSun PLA-lite solid red. I printed rear face in eSun PLA+ solid gray.

Later I printed a second prototype with front face in eSun PLA-lite solid green, external structure and rear face using Creality PLA solid white filament.

I suggest the following print order: front face; main body; rear face.
During main-body printing it would be better to pause the printer (between 50th and 150th layer, at the time you prefer) to slide the front face printed in advance inside the main body. Otherwise, at the end of main-body print the hooks designed to led-strip or ikea lamp make it difficult to slide inside the front face. Rear face is intended to be removable: you can it after assembly of led-strip at any moment.

Four STL included are designed to be compatible with most 3D-printers. My main slicer settings are:
- layer height: 0.2mm
- first layer height: 0.3mm
- nozzle size: 0.4mm
- no s, no skirt, no brim (you could use brim to print main-body structure to avoid warping if using PET-G filaments)

To obtain semi-transarent effect using solid PLA or PET-G some slicer settings are mandatory as follow.

"Front face" 3d-printing settings:
- wall/perimeter loops: 3
- top shell layers: 0
- bottom shell layers: between 2 and 3
- infill density: 0%
- to obtain good finiture I used Archimede pattern for bottom surface, but it's at your choice
printing time: 11 mins; material needed: 7-10 grams

External structure "Main-body" (1) or (2) 3d-printing settings:
- wall/perimeter loops: 2
- top shell layers: between 2 and 4
- bottom shell layers: between 3 and 4
- infill density: between 5% and 10%
- pattern at your choice. I used monotonic
- no brim needed, but you may choose to activate it to avoid warping.
printing time: between two hours and two hours 30 mins; material needed: 70-90 grams

"Rear face" 3d-printing settings:
- wall/perimeter loops: 2
- top shell layers: between 3 and 4
- bottom shell layers: between 3 and 4
- infill density: between 5% and 10%
- pattern at your choice. I used monotonic
printing time: 35 mins; material needed: 20-30 grams
