Scope Cover (41mm inner diameter)

thingiverse

A Scope Cover for the Horizon Scorpion Crossbow. The Coverbase has a 41mm interior diameter and a flexible spring-like mechanism to hold the Lid open and close. You will need two M3x20 bolts and two M3 Nylocks. Print the Lid with 100% infill and Concentric Bottom / Top-Layers for the best results. Print the Base with at least 25% infill and a 0.2mm layer height. If you require a different inner diameter, scale both objects in your slicer. Calculate: (Outer Diameter of your Scope End) / 41 = Scale Factor Example: You need a 47mm ID, calculate: 47/41=1.1463 Scale by 1.1463 (or multiply by 100 for percentage) = 114.63% If you scale significantly, you may need larger screws and nuts. Measure your scope at various points. Many inexpensive scopes are not perfectly circular. Create your scope cover with a diameter 0.25-0.5mm larger due to PLA shrinkage during cooling.
