PARAMETRIC VENTILATED FUNNEL

prusaprinters

<p>If you need a parametric funnel with a bent spout or a funnel with a separate vent tube or just a funnel, you should take a peek <a href="https://www.prusaprinters.org/social/79444-peter-h/collections/119330">HERE.</a></p><p><br>The stl file provided is for a small funnel with a 70mm diameter opening and an 11mm outlet diameter with a 1.5 millimetre wall thickness. (See the SILVER file screenshot above) however you are free to change any of these dimensions to suit your own requirements.<br><br>Note however, the vent is a constant diameter with a constant wall thickness, so at some point if the outlet is reduced far enough it will become smaller than it (the vent). &nbsp;</p><p>All design dimensions are linked to those three criteria so you can arrange an infinite number of combinations while still keeping the basic form of the funnel.<br><br>To modify these parameters you will have to open the document in Onshape. &nbsp;If you don't already have one, you will need a free Onshape account. &nbsp;Open the “source file” link (in small print at the bottom of the download space.</p><p><img src="https://media.prusaprinters.org/media/prints/131942/rich_content/60b15927-b56c-40c5-ad71-93a6446a5bbf/screen-shot-2022-02-11-at-70539-am.png#%7B%22uuid%22%3A%222deba792-246f-421d-92c3-0f83598577b5%22%2C%22w%22%3A1312%2C%22h%22%3A440%7D"><br><br>Modifications are simple. &nbsp;The dimension are at the top of the left hand column and I have provided a few examples above with a red dashed box around the parametric dimensions that need to be modified. &nbsp; Double-click on the parameter you wish to change and then alter the “Value” to the dimension you &nbsp;wish to use.<br><br><img src="https://media.prusaprinters.org/media/prints/131942/rich_content/20a3bba5-07d2-46ba-be1b-d9bc2aa3c5bc/screen-shot-2022-02-11-at-71048-am.png#%7B%22uuid%22%3A%229e398711-3b19-48a5-b95c-4322531df705%22%2C%22w%22%3A810%2C%22h%22%3A328%7D"><br><br>I haven't tried it yet, but printing this in vase mode might be an interesting experiment if you are looking for a disposable funnel for mixing glues or some other nasty substance.</p><p><br>&nbsp;</p>
