Scissor Lamp Adapter 12mm & 13mm ID 20mm OD

thingiverse

I required a clamp/way to mount my lamp/microphone/smartphone scissor extension arm since the original one broke. I checked online but none of the options I found met my needs and took too long to print. As shown in the pictures, this adapter allows me to drill a 20mm hole in my old desk and adapt it to work with either my 13mm or 12mm scissor extension arm. The STL file contains both sizes. I chose 20mm as the outside diameter because I have a step bit that measures up to 20mm, so I didn't need to change bits. You will need to drill a hole in your desk to use this adapter, so be sure you are comfortable with that and ask permission from your parents if you're a kid. Some sanding or resizing may also be necessary if your scissor arm is not the same as mine. This adapter worked perfectly for me and fits very tightly. It's the most useful thing I've made so far.
