About this 3D model

All the cooling fans for the E3D are 30mm that I didn't had so designed my own design also because nothing fitted correctly in my design. I'm building a new printer saw some designs and made my own version of it only the problem I had is that I needed to redesign the hole top part the xy carriage and stuff.And I'm using a E3D full alu hotend the V5 but the standard cooling did not fit it anymore so I made my own design on this because standard it has a 30mm cooling fan but I don't have 30mm only 40 so I redesigned it for 40mm cooling fans :)
