Ender 5 bed supports - Super Struts Remix

This is a remix of jumpshoutmedia`s excellent Super Struts support for the Creality Ender 5. This was already a brilliant thing but I tweaked a few details to make the installation a little easier. In this remix I have: 1.Included nut retention sockets to the support arms to make in much easier to install and allow the use of Nylocks 2.Increased holes sizes by 0.2 mm to make bolt insertion a little easier (this may vary between printer tolerances. 3.Uploaded parts in the correct printing orientation to reduce confusion. 4.Tweaked the back plate symmetrically so it does not require handing. The nut retention apertures are a snug fit so it may be easier to fix a bolt to the nut and pull through from the other side. I have increased the rear boss 1 mm all around to give a little more material to the side of the nut retention sockets. This does not appear to effect the installation or use. Printed @ 0.3 mm layer height, 50% infill and 4 perimeters with Sunlu Black PETG. The parts do not need support.
