Cat Whisker for a Vortex PST 6x24 FFP

thingiverse

This is a 'cat whisker' aka assistance device for more easily adjusting the magnification on a scope, in this case the Vortex PST 6x24 FFP. Can't guarantee it'll fit on anything else. It'll require a M3x6 or so bolt to fasten it. Depending on your printer it may be a hair loose or tight when the bolt is fully tightened. If it's loose then sand a smidge off the mating surfaces where the bolt goes. If it's a little tight then so be it. Went through a few iterations of adjusting the nubs and this one seems to fit well on my particular sample. Your mileage may vary. Print Settings Printer: MendleMax 3 Supports: No Resolution: 0.25 Infill: 30% Notes: I printed this with 3 layers top and bottom and 3 walls at 30% infill in eSun PetG. I found the PetG makes it alot easier to get it on the scope than using a PLA. How I Designed This Measured the outer ring of the magnification ring with a caliper at 44.48mm then counted the number of indentions, 80, then made a cylinder in Studio Max and played around with vertices till I had something that fit. Took 3 iterations to get this design down, the third was just to add indents for the bolt and nut to disappear into the plastic.
