M8 Enclosed Wing Nut

This is a M8 Enclosed Wing Nut. There are two versions.

One is fully enclosed and has 18mm of internal depth. The other has an 'Open Bolt' design and any length M8 bolt can be used.

There is 3mm at the front of the part, enclosing the nut.

A Stainless Steel nut was used (13 x 6.5mm)

To enclose the M8 nut during the print, pause the print at layer 87 (If using a resolution of 0.2mm) with the model orientated on the largest base. Place the nut into the recess and continue the print. (TIP! place the nut on the heat bed prior to placing into the recess to assist with adhesion when printing onto the nut)

Printed with a 'Grid' infill of at least 70%

EDIT: Just reedited the design to remove 0.1mm from above the nut for a tighter fit and better adhesion during 'Bridging' over the nut.
