This was designed for the cheap Einhell TC-RO 1155 E router. It might fit other, very similar cheap models as well or can easily be adopted for them. Fusion 360 files are available for download.

Please refer to the detailed build instructions on my blog.

Print instructions

Print in PLA or PETG. 0.3mm layer height with standard settings and 20% infill work just fine.

When printing the handle.stl be sure to select "supports from base plate only". All other models print without support.
