4x Shorter 5mm-Radius Test Tube Holder

thingiverse

Not an entirely unique creation here on Thingiverse. Plenty of other fantastic alternatives abound. This concept has been around for a while, so I'd make a few tweaks if I wanted to really make it stand out, but let's keep things simple, shall we? A slightly deeper slot for the disc would help keep it in place nicely. I might have overdone it with the fillets just a bit, haha. A family member asked me to design this a while back so they could test fish tank water quality. The 5mm tubes (10mm diameter) they use are approximately 85mm tall. If you genuinely enjoy the design and would like more than four slots, please leave a comment and I'll get right on it!
