Blowgun Mouthpiece/cup

thingiverse

I'm creating my first contribution to share blowgun mouthpiece designs that are currently missing here. I've included two models, one featuring a cone-shaped bowl and the other a spherical one. I strongly believe that an accurate mouthpiece is crucial in building a successful blowgun. Additionally, crafting one without access to a lathe can be quite challenging. To design these pieces, I utilized FreeCad software due to its compatibility with Linux, Mac, and Windows operating systems. I've also modeled it to fit seamlessly on 1/2" Schedule 80 PVC pipes, which is commonly used in homemade blowguns that I've built myself. To facilitate adjustments for various pipe diameters, I've provided the necessary files. Before redesigning the model entirely, I tested an earlier version (version _1) and encountered issues with the fitting. This prompted me to re-design all related files (now labeled "_2"), which include enhanced dimensions on both inner and outer surfaces of the connector piece by 0.1mm, in alignment with my Replicator 2 Makerbot's resolution. Although I have yet to test this updated version (version _2), it is anticipated to be printed within 1 hour and 30 minutes, significantly shorter than my original design time of over two hours. As part of optimizing print efficiency, I reduced the total print duration. Regrettably, when printing version _2, the part would often warp off from the build plate. To address this, I introduced additional helper disks for stability during the print process and added another fillet inside the mouthpiece to secure its shape accurately on the build platform. Notably, I used Ninja Flex 2 material while printing the mouthpiece, which has flexible properties, and the results came out very well!
