I was in Wal-Mart and saw a table for $10 with virtually the same dimensions as the IKEA table so I got it.
I got it home & found out it was about 1" too short. No worries. Thingiverse to the rescue.
I found Zuspiel' design and modded it a bit for myself. The table legs on the IKEA are 50mm square I believe. The Wal-Mart table legs are 45mm square. Plus Zuspiel' leg extensions are 60mm high I believe. I made this one 75.
I added a 2nd corner bracket to mine so it would fit on snugly. I eliminated the holes too. If needed later I'll just drill them out.
If you would like any mods made to yours, please let me know & I'll see what I can do.
I used only a 20% infill because there won't be that much weight on top of this thing. Even at 20% this is extremely sturdy. You can go higher, but it's not really necessary I don't think.
123d Design to the rescue...
I used 123d Design to make my adjustments.
