This is a long version of brix's parametric rod clamp. It allows heavy-duty clamping with a lot of bolts.Print or modify parameters and print. Use to bolt something to a 8mm rod with m4 bolts. It's 86 mm long and uses 5*2 bolts per clamp.This works well for stiffening the Prusa frame in the X direction. By clamping a plate using these to the top of the frame, the amplitude of vibration is reduced to a fraction compared to the stock frame. May reduce the vertical print area depending on the extruder setup.
