Thanks to @Cheesus and @KimAndersen_718671 for the lamp :)
The author remixed this model.
This is a version of the model from @Cheesus that keeps the size of the model upscaled by @KimAndersen_718671 and it is mostly intended to make the lamp more efficient. Reduced the amount of material from 1.2 kg to around 0.6 kg.
The inserts and upper ring have been modified removing superfluous material to save filament.
The upper ring has been redesigned to improve ventilation and avoid blocking light.
The slots for the petals have been modified to 0.4 mm. I used thinner petals and translucent materials for better use of the light. Nevertheless, the construction will likely allow 0.6 mm petals.
The lower ring was modified too to save material and block less light, but it turned out that the lamp was sturdy enough without the ring (The ring is still included as “deprecated” just in case some reinforcement were necessary)
Used the petals from @KimAndersen_718671 scaled down in the Z axis. Included the files for the petals arranged to fit 3 small petals or 2 large petals in the build plate of the Prusa MK4
Edit:
The quantity and layout is the same as the original:
Lamp Petals (Large) x 20
Lamp Petals (Small) x 40
Row 1-4 small petals
Row 5-8 large petals
Row 9-12 small petals
Nevertheless, after some time I decided to replace the 4th row with large petals for a bit better coverage even though it doesn't make a big difference. That would be:
Lamp Petals (Large) x 25
Lamp Petals (Small) x 35
Row 1-3 small petals
Row 4-8 large petals
Row 9-12 small petals
The rows are counted starting from the light bulb side.
