Set of small funnels, spiral vase mode printable

prusaprinters

<p>I was looking for a funnel printable in spiral vase mode, yet among the 200+ models found on prusaprinters there was only one that was spiral vase suitable and unfortunately didn't fit my dimensional needs. So I made some models on my own.</p><p>Why is spiral vase mode so important for this application? Well, it's the only safe way to achieve impermeability to liquids for the walls of a single wall print*. Thus it saves at least 50% of material and printing time compared to multi-perimeter designs while still being superior under hygienic aspects.</p><p>This set contains five predefined sizes of funnels with the following diameters (outer dimensions):<br>80 mm - 10 mm - 7 mm<br>60 mm - 10 mm - 7 mm<br>60 mm - 6 mm - 4 mm<br>40 mm - 6 mm - 4 mm<br>40 mm - 5 mm - 3 mm<br>Of course, all models can be scaled to fit individual needs.</p><p>To print them in spiral vase mode, you should use<br>- a perimeter size that's at least your nozzle's width and<br>- a layer height that's ⅓ (or less) of your perimeter width.<br>So, with a 0.4 mm nozzle, it's best to use a layer height of 0.15 mm with a 0.5 mm perimeter or 0.2 mm with 0.6 mm. Top and bottom layers both have to be set to 0.<br>At 0.2 mm layer height, one funnel will take between 12 and 33 minutes (depending on the size) to print.&nbsp;</p><p>Concerning filament material: This depends on what liquid you want to use the funnels for. PETG is generally not a good idea for objects with short layer times, ABS will dissolve when used with some solvents (or varnishes containing solvents). PLA (as well as LW-PLA and lignin-based biopolymers) is safe in both respects, so in most application cases it will be the material of choice.</p><p>&nbsp;</p><p>* I have to add that this is true for FDM printers only. If you have an SLA printer like the SL1S, you don't have a spiral vase mode (nor could you use it at all) and can't use these model files.</p>
