I've bought IKEA UTESPELARE table and STUBBERGET monitor bracket. They looks really good together and works just fine, however I've noticed that table mesh was bending under the weight of monitor.
This little support is almost invisible from user perspective, but fits just under the bracket and make it much sturdier. Also it provides additional support for the mesh, so it is no more bending.
Model itself does not need much support or does not need to look to fancy. I've printed mine with PETG 0.3mm layer height and 20% grid infill (0.3mm DRAFT print setting in PrusaSlicer).
The author marked this model as their own original creation.
