Customizable table/chair leg extender 

 

This practical model can be used to raise tables and chairs. Perfect for raising children's furniture when your child has outgrown their table or chair. There is a version for square legs and a version for round legs. You can use the “Customize” button to adapt the model to your tables or chairs. And, of course, you can also choose the height of the extension. 

 
Feature overview: 

  • For rectangle or round furniture legs 
  • Costumizable to fit your furnitur legs 
  • Choose your needed height of the extension 
  • Stable and inconspicuous design 
  • Can be attached with double-sided adhesive tape and/or screws.  
    For chairs, I recommend using a screw. 

 

Customize instructions: 

Click on the “customize” button and enter the dimensions of your furniture legs and the desired height of the extension.  

You can also change the height of the frame. Standard is 30 mm, as I have achieved good results with this value. Therefore, this value does not normally need to be adjusted. 

 

 

Print profiles: 

I created the extender for an IKEA Kritter table, an IKEA Sundvik chair, and a stool with round legs. There are ready-made print profiles for these three applications. Use the generator to create models for your own furniture. 

  

Dimensions of the print profiles: 

- IKEA Kritter table: 30.8 x 30.8 mm / 50 mm extension 

- IKEA Sundvik chair: 30,8 x 30,8mm / 20mm extension 

- Round: Ø30,8mm / 20mm extension 

 

Print settings: 

  • 3 Walls 
  • 0,24mm Layer height 
  • If you use it for adulds chairs you can increase the infill and walls for better stability
