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. The PLA 3D printed extension measures 90mm (overall length) x 28mm (centre width). It fits modern doorknobs which measure 28 mm x 13 mm (x 14 mm depth).

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, check our range of products here (items for sale by campermates). 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.

If you are not sure which model of doorknob extension would fit your doorknob, please send us a message with photos and dimensions of your doorknob and we can advise you.

Customer Reviews:

“This is a game changer invention for anyone who has a slam shut composite door with inner knob turn. Currently my wife and children have experienced great difficulty opening the door from the inside. Thanks to this simple device the problems experienced have been resolved. Excellent product so happy to recommend to anyone experiencing similar issues.” - imyurman

“Very pleased with this product. The seller helped enormously by keeping in touch and suggesting a different size. That was very helpful. The original door catch design must be for professional athletes not old age pensioners with not so strong wrists. This modification is ingenious. Thank you” - regweir2010

“Absolute game changer ! Really really delighted with this. It fitted securely with tape as instructed and my wife has stopped complaining about the stupid doorknob. Thank you. One small improvement, our knob has a button in the middle which needs to be unpressed or the key wont fit from the outside. Not a problem, but if there was an option with a 12mm hole on the centrepoint of the knob then this would be even better in our case. :) Thank you again” - silverrangerover
