My old collector has been giving me issues, so I designed a new one that bolts into a 5 gallon bucket. It's easy to print, easy to assemble, and works very well. I've published it to thingiverse for others to enjoy. There are a few adapters published that include the HFT Bauer mini shop vac (for suction) and 1.75" utility hose that is standard to most regular shop vacs.
Not sure why the link didn't stay, still new to Lemmy...
