Twist Clamp 3-Inline BCAR (5/8" to 16mm)

prusaprinters

A general-purpose Nerf BCAR meant for 16mm OD barrel mounts.  Features a barrel clamp to secure into place and a thumbscrew designed for extra leverage. Requires 12x M3x8-12 bolts, 9x F683ZZ 3x7x3 bearings, one M3x20 bolt and one M3 hex nut.Source files are included and are parametric on angle and crush. Angles between 10 and 4 degrees are available, with 10 being reduced crush (20.4mm), 8 20.2mm, 7 and 6 being 20mm, and 5 and 4 being increased crush (19.9mm and 19.8mm respectively). This corresponds to a effective “crush” of about 12.3mm, 12.2mm, 11.9mm, and 11.8 and 11.7mm. Keep in mind that these higher crush lower angled options will knock off 10-20 FPS, but the crush helped me get the results I wanted.Anecdotally, myself and some locals were able to get it running quite well with DZ Ruby Max though I've had much more mixed results with Worker HE (which has been a problematic dart with batch variation).
