About this 3D model

this is a dove tail support for vintage celestron C8, to enable easy and fast finder connection and exchange. a M4 bolt (both screw and nut) is needed as it fixes the finder. I suggest to print it in PETG or ABS (I use PLA only for home objects), "flat" on the printer bed with adeguate supports, 3 or 4 walls and infil 35%.
