This is a mounting plate for the right side of the EQ6R-Pro for a dovetail. You will need 3MM x 25 x3 screws and a 3mm x 10 to account for the additional 3mm of thickness in the plate. Recommend to use 4 shells and 50% infill for stability and strength. I used PLA.

Here is the dovetail I used: https://www.amazon.com/dp/B01EOET7DS?psc=1&ref=ppx_yo2ov_dt_b_product_details

You will need longer 5mm screws as well.

Enjoy!
