Rega RB300 Tonearm Spacer

thingiverse

To use a Denon DL-110 cartridge on an RB-300 tonearm with a Rega P3 turntable, a 3.7mm spacer is needed due to the height difference between the cartridges. This spacer doesn't require additional nuts for installation. For a Nagaoka 110, a 2mm spacer may be necessary (needs verification). Simply print the spacer in ABS with 80% infill and ensure its top surface is flat. Remove the old cartridge, fit the spacer on the tonearm's cables and base, reassemble the tonearm onto the turntable, mount the new cartridge with proper alignment, and enjoy your records.
