prusaprinters

<p>Funnel stop design for microscope objectives, fully customizable in OpenSCAD</p><p><br>It offer many options to fit most objectives; can also generate other stops like Condenser darkfield stops, eyepiece field stop etc.</p><p>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.</p><p><br>For OpenSCAD, don't forget the JSON file that has the nice presets - it is at the bottom as .txt</p><p>Loaded here also some ready made &nbsp;STL designs for eyepieces I've used.</p><p>&nbsp;</p><p>&nbsp;</p><p><strong>Printing:</strong></p><p>Designed to be printed straight away without supports or rafts. &nbsp;<br>I used PLA; also other materials may go well if they allow good precision.</p><p>Those are SMALL things with fine details, they need precision, show your skills, best is use the smallest build height and ridiculously slow speed.</p><p>The fine screw threads may need 2-3 trials before getting them right, as they need to hit 0.2-0.3 mm precision.</p><p><br>Some designs (tall, thin) &nbsp;may like a brim, most don't need. &nbsp;Do NOT make a raft.</p>
