Bosch RA1181 Insert Ring Shim

SummaryOn my Bosch RA1181 router table, the inset rings (red hole caps) are not flush with the table top. They are low by about 0.4mm. So a created a ring shim that installs nicely on the back of the insert rings. I made it 0.4mm thick but you can adjust the Z axis in the slicer to work best on your table.Printed it with 0.08mm layer height and in prints in a minute or two. 3/16/2025: Added a second profile that significantly improves the z height (thickness) accuracy.
