Minolta MD Macro Extension Tube

thingiverse

I've been interested in macro extensions for my Minolta for a while now, but even the cheapest ones on ebay seemed pricey for something I was probably going to use a few times and forget about. Enter 3D printing! I mushed together MersennePrime42's body cap and jkenny23's MD adapter in Blender, both really nice models. I hope you don't mind me using them for this project. I'm not sure exactly how long of an extension this is, but it lets me focus pretty close, within an inch or so I'd say. I'm sure it would be easy to edit the STL in Blender to make it longer if you want even MORE macro. I need to figure out where the alignment dot is supposed to go, cause currently it's a bit challenging to figure out exactly which way up the extension and the lens are supposed to go.
