Skiball Style Target Rings

prusaprinters

I made some target rings to create a game out of the launchers made by Nakozen. The STLs have a 0.2mm clearance on the threads (0.1 removed on opposing sides). If this is still too tight for your printers tolerance, let me know and I can easily add some more loose locking nuts.Additionally, you can edit the parameter in the fusion 360 file to edit the clearance easily yourself.Printing:You'll need a locking nut for each target ring you install.The target rings have 2 parts, the ring itself and the numbers. If you have a multi-material printer you can easily print it all together.If you don't have a multi-material printer you can just print the ring without the text.I used 0.2 layer height with a 0.4 nozzle, but it should work at other layer heights and nozzles. Only thing worth noting is the text is only 0.4mm tall (2 layers at 0.2 layer height).Assembly:In addition to the printed parts, you'll need a cardboard box and optionally some plastic grocery bags for this.Cut holes in the cardboard box so that the point ring can fit through.On the back side, secure the ring to the box using the locking nut. (Optionally, use the locking nut to secure a bag to capture the pieces as they are shot into this target)Modify the open flaps to create an angled base, or just prop it up somewhere.
