About this 3D model

I wanted a dust shoe that could have its height set independently of the Z movement so I came up with this. Video of it in action: https://www.youtube.com/watch?v=Cq3LlhZMwkM In the STEP file are two options for the shoe. One is 3D Printed, the other can be machined on the PrintNC. The printed shoe needs a machine with a 300mm bed size so I recommend going for the machined version. You can use 10mm perspex. To complete you will need the following stuff: For the 3D Printed version: 2 x 8mm smooth rod approximately 150mm in length 16 x M4 x 20mm bolts 10 x M4 nyloc nuts 1 x Dust booth brush 4 x LM8UU bearings 12 x 8mm x 1mm magnets For the machined version: 2 x 8mm smooth rod approximately 150mm in length 16 x M4 x 20mm bolts 10 x M4 nyloc nuts 1 x Dust booth brush 4 x LM8UU bearings 12 x 8mm x 2mm magnets
