Dad's Funnel, Large and Small Size, Its a round funnel with a rectangular end.

My dad needed a rectangular-ended funnel, as shown in the images with metric dimensions.\r\n\r\nThe large funnel is 125mm tall, its end has a diameter of 150mm, the rectangular part measures 25mm x 50mm, and 25mm long, with everything being 5mm thick, but printed it appears to be about 2.5mm, likely an error on my part.\r\n\r\nThe smaller funnel is also 125mm tall, its end has a diameter of 100mm, the rectangular part measures 25mm x 50mm, and 25mm long, with everything being 5mm thick, but printed it appears to be about 2.5mm, likely an error on my part.\r\n\r\nWhen I 3D printed the funnels, the wall thickness was around 2.5mm instead of 5mm, not sure what happened, but they work fine and print well for me, guess I need more practice LOL \r\n\r\nI included a push block, it's 15mm thick, 40mm wide, and 100mm tall.\r\n\r\nThese funnels were made using Punch! ViaCAD 2D/3D v10, along with its save file, STL, and STP files.\r\n\r\nWhen creating the smaller funnel I used different tools within Punch! ViaCAD, but it failed to export correctly to STL, exporting to STL distorted the shape inside of Punch! ViaCAD, however the STL file looked good in Cura, but when printed it always came out as a solid shape instead of a funnel, found that you can export to STP from Punch! ViaCAD, then import the STP file back into Punch! ViaCAD, then export to STL, and finally the file looks correct and 3D prints correctly.
