I made this model for a outside storage box for bicycles it basically protects the feet or underside corners from damages of the ground.
However i made it in such way that it can protect all kinds of furniture boxes etc.

Its 30x30 and scaleable simply scale it in the X and Y directions equally and it enlarges for bigger feet or corners.
It has a center hole centered on 15x15 to allow screwing it to the object that needs protection.
It not only protects the bottom but also the sides of the corner.

its printed with default infill and infill pattern i tested it with R3D black and Jupiter series 123-3D filaments on a outdoor box.
Its Strong and can withstand a lot of hits or bounces. and cannot be bended.
I printed in in PLA and PLA-CF both equally strength it seems.

Print settings that are optional but recommended:
25% infill
300mm inner and 60mm outer wall speed.
3 walls
3 bottom and top layers

no supports needed.

Be sure to post a picture of it in use i would like to see others enjoying the use of it as me.
