Have some spares of some calibration packet holders I designed and 3d print. One is storage of spare packets and the other holds the packets in the sump to get them to temp for and during calibration to increase accuracy. I've posted the examples from my own use. The last pic is the colors I've got on hand and a couple of other reef items I printed. The packet holders are $20 each. Message me if you're interested in the other items and I can shoot you a price. If you want another color I'm happy to custom print it for an additional $5, prepayment required. I live in the Lakewood/Green Mountain area but will ship for actual cost at buyer's expense.
