DISCLAIMER: I am in no way affiliated with Konica Minolta.I needed this for an upcoming experiment and haven't been able to find it as an item sold by KM, so took an afternoon to model it. Hope it's helpful if you somehow are in the same situation! This is a petri dish holder/jig designed for a Konica Minolta CM-26dG spectrophotometer/colorimeter. This jig facilitates repeatable and secure measurements of pastes and liquids in a 55 mm Konica Minolta mini petri dish, modeled after the part shown in this video from what seems like a KM Asia technical rep: https://www.youtube.com/watch?v=wUAAsZxpFwM It is recommended to print this with the legs sticking up in the air, and with supports turned on. Tree supports worked best for me. The height of the well bottom should be slightly below the level of the lens, so the petri dish can be in full contact with the instrument.To use, calibrate as usual, turn the instrument upside down as shown in video, settle legs fully into screw insets (with part contours matching contours of instrument), place sample/petri in well, and press side buttons to record a measurement. I fill petri dish with 10 g of my sample, which is about halfway full in this case.
