Happened to me more than once where the weighted base of a floor lamp breaks and crumbles in small pieces.

Here I replaced it with this new plastic base.

• The shape of your base may (will most likely) vary from mine.  Use the provided STEP files to alter the shape for your lamp
• The 4 pockets and lids are to allow adding weight to the base with the material of your choice
• Base is slit to allow the installation without having to remove the power cable

Printing details:

• I printed mine in ABS but any material will do
• Qty required is approx. 260g
• I used 20% infill
• STL already oriented correctly
• No support required
• Size of the part is 200mm dia x 75mm high
