Caliburn Rail Riser
thingiverse
Version 1 (for monolithic magwell - R3 caliburn) An integrated rail riser for the Caliburn top rail. Doesn't need much infill. Printed mine at 0.8mm borders and 20% infill. I'd suggest printing with supports unless your machine is great at bridges. Does not solve wobble issues with the top rail.
