QPS-Open version for larger 3D printed Nerf blasters.

DESCRIPTION The QPS-Open Sight is a New version of my original Quick Point Sight with separate adjustable fore sight part aimed at larger 3D printed blasters such as the Tempus blaster. It is setup for Nerf blasters which have a larger amount of dart drop over distance. Useful both for teaching basic sight adjustment & also for Nerf battles. Attachment is for Picatinny rail.

DESIGN NOTES This is two part sight based on my original QPS design, with the rear sight using parts from the original. Original QPS design is available here:- https://www.thingiverse.com/thing:4705126

3D PRINTING NOTES Generally print out using typical PLA 0.2mm layer height, 30% infill settings, No supports. The Front Mount & the Aft Top Lower parts do require supports for the M3 nut recess (the STLs are marked). The Fwd Sight, Sight Adjustment, and Rear Sight parts do benefit from a finer layer height of say 0.15mm.

ASSEMBLY NOTES See Photo build guide pdf.
