Funnel stop design for microscope objectives, fully customizable in OpenSCAD


It offer many options to fit most objectives; can also generate other stops like Condenser darkfield stops, eyepiece field stop etc.

The Funnel models are designed to be printed from the base up; the other models from the tip up. They are already oriented correctly, z+ up.


For OpenSCAD, don't forget the JSON file that has the nice presets - it is at the bottom as .txt

Loaded here also some ready made  STL designs for eyepieces I've used.

 

 

Printing:

Designed to be printed straight away without supports or rafts.  
I used PLA; also other materials may go well if they allow good precision.

Those are SMALL things with fine details, they need precision, show your skills, best is use the smallest build height and ridiculously slow speed.

The fine screw threads may need 2-3 trials before getting them right, as they need to hit 0.2-0.3 mm precision.


Some designs (tall, thin)  may like a brim, most don't need.  Do NOT make a raft.
