Scope Cover (41mm inner diameter)

thingiverse

A Scope Cover for the Scope of my Horizone Scorpion Crossbow. The Coverbase has 41mm inside diameter and a little flexible springlike mechanism (see picture) to hold the Lid open and close. You'll need two M3x20 bolts and two M3 Nylocks. Print the Lid with 100% Infill and Concentric Bottom / Top-Layers looks best for me. Print the Base with minimum 25% Infill and 0.2mm Layerheight. If you need another inner diameter just scale both objects in your slicer. Calculate: (Outer Diameter of your Scope End) / 41 = Scale Factor Example: You need a 47mm ID calc: 47/41=1.1463 Scale by 1.1463 (or * 100 for %) = 114.63 % (If you scale a lot, you may need bigger Screws and Nuts !) You should measure your scope on different points. Most cheap Scopes are not 100% circular. Create your scopecover around .25-.5 mm bigger because PLA shrinks during cooling.
