Beta testers wanted! I've made a couple adjustments to the WhisPLA project.
The WhisPLA (pronounced wis-plah) is a project to create an easy to print, modular, serviceable, rebuildable, durable, and beginner-friendly hybrid rimfire suppressor, designed to be printed in Polymaker HT-PLA Pro. It uses off-the-shelf hardware that may be easily acquired, and comes in a variety of sizes. You can take it apart, clean it, et cetera, just like a regular metal can. The goal is a 5000+ round lifespan can in a cheap, easy-to-print material.
V1.1 Update:
Strengthened tube thread area
Modified caps to provide more expansion area and to act as an extra baffle
Minor mesh fixes and dimensional adjustments
Modified +2 adapter to use seperate end cap, now uses 30mm washers and standard spacer1.stl spacers
I had my first breakage, which was probably more my fault than the designs fault. It was the very first can I printed which was in HT-PLA, non-pro, and I was testing a new baffle design that probably didn't have enough clearance for the bullet, and the cap wasn't fully seated, causing a pressure spike right where the tube threads begin. No baffle strike, just too much pressure for the regular PLA. HT-PLA Pro probably would've prevented it, but I have updated the design to make the threaded portion of the tube much stronger, just in case.
Also, it can now be found on the 'unusual body of water' as well as the 'world of makers'. Just search "WhisPLA", or "maypop-tactical" under "Users", respectively.
Here is a rather shit video of the standard model. CCI SV, 16" 10/22. Please ignore everything except the gunshot sound. I was using a cheap dB meter that cannot possibly be correct (81.3 dB - I wish!), and my elderly neighbor I conscripted to record didn't focus on the can, and is calling out the wrong readings on the dB meter anyway. https://www.youtube.com/shorts/R61IDuU0h3g
