Astra Lumafloris - Lamp with upcycled Prusament spools

Introduction

The 3D printed lamp business is growing. It's cool, but it creates a lot of plastic waste compared to injection molding. To reduce plastic waste, I made a design that allows you to upcycle one and a half Prusament spools per lamp. You only need to add unprintable electrical hardware.

BOM - Printed parts

- 1x Base
- 1x Base_with_thread
- 3x Block
- 3x Clip
- 3x Cover_Outside (optional, only for older version of Prusament spool)
- 3x Cover_Inside (optional, only for older version of Prusament spool)

BOM - non printed parts:

- 1x Bulb socket with cord and plug
- 1x Bulb

Printing settings

I recommend using PET-G for printing due to its thermal resistance. Also, I highly recommend using only LED bulbs because they create less heat than traditional bulbs.
Brim is required for printing Bases. Inverted "pyramid" shape causes wrapping corners. You can print without brim if first layer adhesion on your buildplate is really high.

Settings that I used:

Assembly manual for optional side covers (only for old Prusament spool):

The best way to cut that hole is using a rotary tool with a proper cutting disk. As long as the hole diameter is between 90mm and 100mm, every imperfection will be covered from both sides.
I cut mine on a CO2 laser with high power and low speed. Since the Prusament spool is made from material that is not "CO2 Laser friendly," I had to cut some bridges by hand.

Disclaimers

Please use the "add text" option in the slicer of your choice and add the material symbol according to local laws about product safety and recycling.
