Do you find it hard to twist your inner doorknob to open your front door? I had the same problem and could not find any knob extensions anywhere in the market. Considering so many people are struggling to open their doors easily, we have come up with the idea of 3D printing an easy to use inner doorknob extension.
It fits modern doorknobs from Green TeQ but not limited to, which measure 32.1 mm x 17.5 mm (as shown in the second photo). The PLA 3D printed extension measures 88mm (overall length) x 28mm (centre width). If this extension doesn't fit your doorknob, we accept returns within 14 days.
Hope this little gadget will end your door-opening frustration and give you a comfortable knob-twisting experience.
Please note the doorknob extension may have some production marks which do not affect function.
If you like this idea but have a different doorknob, we also offer a bespoke design service for your provided specifications with a small fee. We'll work with you to develop a new handle extension to solve your problem. Please contact us for details.
