Desk Cable Grommet and Plain Insert (for 76mm hole)

prusaprinters

I found other models of desk cable grommets, but none that I liked were for a 76mm hole saw (which is a standard size included in many cheaper hole saw sets in the UK). So I modelled this one while making new desks for our children.You don't have to use the insert (see photo of one I've used in my workshop without a grommet).I recommend printing both parts upside down, with an internal brim for the grommet and an external brim for the insert.The examples in the photos were printed on an Elegoo Neptune 3 Plus in eSun ePLA-Matte black and ePLA-Matte white.  They were both printed with a height of 0.08mm for the first 0-2mm, to create a smoother definition on the visible faces once inserted, with the rest of the object printed at 0.20 mm. Tip:  I also printed these in quick succession with a 3 loop skirt @ 10mm (to help clean the head away from the nozzle) and a 5mm brim.
