A K'nex/TinkerToy/underfloor heating inspired solar heating system for your small outdoor pool. Mine takes a 500 gallon pool from 65F to over 90F in one sunny Colorado day when used with the black pool cover. I filled a 5 gallon bucket in…
Our safety department didn't think zip ties and orange streamers were good enough so they wanted us to get something more official for locking out valves. The official products sold on sites like Grainger are also plastic and would be…
Most of our dip cups were broken or cracked. I went to but new ones and didn't like the price. We have stacks of PVC pipe (what plant doesn't) and it's cheap anyway. You will also need 2 screws (I used M4 stainless) and probably some 1"…
UPDATE: 9/29: added hollow nose cone and fin sections and thinner hollow midsection as I had challenges printing one at 273% (max for the MK printers) I wanted one that was easier to print, without supports, and has fin options and the…
A simple little design to help the stubborn fittings come apart on smaller diameter tubing found on small water systems or instruments.
The rollers require 4x 608 bearings and 4x M3 x ~12mm screws. Print 4x bearing rollers and retainer washers The filament guide needs 2x M3 nuts and M3 x 10-12mm screws, and one M10x4mm PTFE fitting. I'm using 2.5mm ID tubing and securing…
The spacers in my opener went out, so I fixed it, for next to nothing, 3 hours later. OEM kit is about $10 with 5-7 days shipping. To get them close to the OEM "durometer" or function of the original spacers (soft start on the plastic…

My little one (not the cat) likes the longboard. Now he has something to hold onto. Hole patterns for both old and new and will work with your spare board hardware (but longer) or M5. I printed this out of CC3D 72D because it has some…
It always bugged me this wasn't wall-mountable. I thought, surely someone made a wall mount for this. Well now here one is. Best printed out of at least PETG, 4 perimeters gets the side clips to a solid wall. The holes should fit most…
Turbidimeters can clog and lose flow over time. These will help get a quick visual of the flow and allow for a sample grab without touching the 1/4" drain line. Our filters read as low as 0.013 NTU and it is very easy to contaminate water…
The filter media in our Biofilters is 17 feet below the filter deck under 10 feet of water, so grabbing a sample of filter media is tricky. This spear stabs into the surface and pulls out a good sample for analysis. You will need a 3-4…
This 2-piece insert threads together and allows you to drain something all the way to the bottom. Use silicone glue on the outer piece flange and threads when inserting and assembling it to make it waterproof. use a zip tie around the…
AWWA guidelines recommend 20% - 30% expansion of the filter bed when backwashing conventional filters. Here is a tool I made to measure the expansion. Basically, you have a weight at the bottom of some 3/8 threaded rod and secure a stack…
