Hey all,

**Edit - all source files for this are freely available on Thingverse, search RobBzReef**

I've been itching to get into the 3d printing world as an outlet for enjoying creativity and solving problems. For my first project I choose to make a stand or caddy for my Hanna checkers. This can sit on a table top or be mounted to a wall, your choice!

There are essentially two versions:

v3 which is designed to store the cuvettes with the lids on and it is not compatible with either the alkalinity or the calcium test.

v5 which is designed to store the caps to the cuvettes on the side of the caddy to facilitate drying and it is compatible with the alkalinity and/or the calcium test.

Both versions hold a total of three testers, two cuvettes for each test, powder packets for each (around 20), a space for the destructions, (3) 5 ml syringes, (3) 10 ml syringes and a wall mount plate. Alk and CA compatible configurations also hold the 1 ml syringes and the 100 micro liter syringe for the Ca test.

Versions + configurations:
v3
1) 3 tests (no Alk or CA)
a) All text embossing is editable

v5
1) 3 tests (no Alk or CA)
2) Alk & CA + one other test
2a) this option requires the center powder packet slot to share with the 'other' test but it has been enlarged for this
3) Alk + two other tests
4) Ca + two other tests (not Alk)

All configs have easily editable embossing for you to customize.

Notes: The pads in the corners are to help with first layer adhesion, I simply cut them off with a razor after printing. This is only mandatory if you're going to mount it to a wall of course. In the source file I put the sketch for the text embossing at the assembly level so you don't have to drive into the component level. At the assembly level use the selection sets to simply turn the various configurations on and off. I used Fusion 360 to develop this. It's free to use and powerful.

The source files for this and a few example .stl files have been uploaded to Thingverse. Search for me (RobB'z Reef) and you should see it. 'Hanna' might return something too, I can't recall.

Please feel free to download this, modify it, print it for yourself or a friend, look at it and wish you had a printer or ignore it altogether! I do not condone or grant anyone permission to make this and sell it, especially if you're a business. It's intended for hobbiest use and not for profit making. If I catch you making and selling this, I will come find you.

Other than that I hope at least one person finds this useful. Enjoy!

@ReefSquad somehow I accidentally posted this in buy/sell ironically it's absolutely NOT for sale. I meant to post it in the 3d printing forum which i thought was not under buy/sell. Can you help move it somewhere not in the buy/sell area(perhaps DIY?)? sorry about that!

Very cool... I want one. Who can print one for me? I am definitely willing to pay/donate. :)

I would like white. Ca, alk, PO4 and minus the other text.

I really am sick of balancing all my test stuff on the tiny shelf next to my tank.

That looks great. Do you know approximately how much that would cost to print in supplies cost? I have a friend with a printer and wondering how much it would cost to print.

It's about 490g of material. He can figure out the cost from that or half a 1kg spool of filament. The one in the photo is about $12 in material.

That sucks you wont sell it, I would buy it in a second.
Sorry, I'm not in the hobby for profit, just for fun and gaining friends! I put this here for everyone to be able to make it for themselves. Do you have a printer or a friend who does?

I printed it at 10% with a 3 perimeter min. it's plenty strong at that. Fully loaded all the testing materials are only around 400 grams themselves. Possibly a bit more with the Alk/Ca tests so it's not holding up much for weight. I'm using the Prusa slicer 2.3 and it estimated at 490 grams. My goal was to be able to get two units from a 1kg spool.
