About this 3D model

I pre-ordered the Eibos Polyphemus filament dryer, which came with an expansion rack for 3kg spools. Unfortunately Eibos QC is a bit suspect, and the corner pieces provided with the expansion rack were too short, around 35mm in length. My rack required 40mm corner pieces. (Dimensions: 13mm x 13mm x 40mm.) Have not seen similar models on Makerworld, so sharing this model so that others can just print this part if they need it.
