About This File
This sketchup file produces a 3D model of a robust (chunky) classic gun rod collar when exported to STL & the 3D printer of your choice.
The reason I have uploaded it as a Sketchup file (in a zip format), is that if you select the whole model, then press , the model is surrounded by a cube which allows you to increase or decrease the overall model size, allowing you to tailor the inside diameter of the collar, to the outside diameter of the gun barrel.
It allows for about 5mm depth of support for a gun rod (once drilled out to suit your rods) to be affixed with epoxy resin of similar.
Earlier versions of the file produced one defective gun rod support - This model has extruded all pushed all the outer faces of the supports back into the main collar in a attempt to correct that defect. Should that not be the case, then I will create a new model when I get chance.
In HQ 0.1mm layer height & 5% infill it takes about 1.2 hours to print on a Makerbot Replicator 2.
