Desk clamp for work lamps, magnifying lamps, etc.

Jogi's Desk Clamp for Desk Lamps, Magnifying Lamps, and More

This C-clamp was designed for my old desk lamp after the original clamp broke

This one is printed in PETG-HF (a material I highly recommend), but should also be printable in other materials

While 3D prints shouldn't be overtightened, this part holds exceptionally well

For printing, use 4 wall loops, 6 top and bottom layers, and at least 25% infill; honeycomb is quite stable
These values can be increased if desired


There are 6 print plates, only ONE is needed
The clamps differ only in the lamp hole size

My lamp has a 13mm diameter; other common sizes are 10mm, 12mm, and 14mm—measure your lamp and select the appropriate holder; you do NOT need the others

Slide the screw and pressure plate onto the plate of the selected holder, or print them separately (better, but slower)

The pressure plate consists of 2 parts that are printed IN PLACE, meaning they interlock but are not permanently joined

Neither brim nor support is needed; do not change the orientation of the parts

After printing, screw the screw through the holder, attach the pressure plate from the other side, attach the part to the tabletop, and tighten—do not overtighten

If it holds—insert the lamp—turn on the light

Suitable for tabletops up to 30mm thick

Update 30.4.2025: Alternative screw added: Narrow head
