I have an Ikea desk (dunno what model is) that is very wobbly and with printers on it shakes a lot so i've made these legs bracket to reinforce it and keep legs squared.

they should also work in Lack tables and other kinds/models with 40mm squared legs

a bunch of self tapping screws 3.5x13mm are required 

2 left and 2 right parts needs to be printed for 1 table 

for the missing version files just mirror it on your preferred slicer! for my personal use I've printed V2 version left and right in HS PLA
