About this model

Simple 84mm ring compressor. Requires M8/M10 bolt and nut. Suitable for M50/M52/M54 B25/B28/B30 BMW Engines. Align the print seam outside the contact patch with the piston. Print in PETG or ABS. Oil up the part before use with engine oil. Do not over-tighten it, when the flaps start bending stop tightening. Step file provided for easy readjustment. Worked flawlessly with my M54B25 build!
