About this 3D model
These tiny versions of my compliant mechanism clips are only 15mm wide and yet they're functional! It's an easy print, no supports required, works right off of the bed. I printed mine with PLA at 100% infill. PLA will lose clamping strength if left in the open position for a long period of time, especially at higher temperatures. ABS or ASA may be suitable options. Leave a comment if you have success with another filament!
