This modular hydroponics tower lets you grow a large amount of plants without the need of lots of room. Each module fits 3x 50mm (2 inch) pots and has the water tube running up the middle. Just stack as many modules as you require.&nbsp;Each module is designed to fit 3 M3x4x5 heat-inserts and bolt together using M3 x 6mm bolts.&nbsp;I designed this to fit on a small 3D printer, with a build area required of 170 x 170.&nbsp;At the bottom of the stack you need the Base with a 16mm barb fitting and the optional base clamp (to clamp to the other side of a container lid) and attach it to a submersible pump.&nbsp;At the top you push in the shower head and bolt on the lid. I drilled out the holes of the top module to 4.5mm to fit in 3 heat-inserts to make this secure but it does function fine without the lid bolted down.&nbsp;Have fun growing!

Everyone is familiar with the various types of cable grommets for furniture panels. With Conduito, you now have the option to use a version specially optimized for 3D printing. By carefully studying existing models, I developed a variant tailored for 3D printing. This design allows you to produce a cable grommet directly with your own 3D printer.&nbsp;Conduito is available for a variety of hole diameters, from 1 3/8 inches to 4 3/4 inches, including common sizes like 1-3/4, 2, 2-1/2, 3-1/8, 3-3/4, and 4 inches, as used by Forstner drills, for example. Calculating the diameter of the cable grommet is straightforward: hole diameter minus 0.39 inches. The panel thickness should be at least 0.59 inches.&nbsp;Complete information about this project, including links to both free and licensed versions, is available on its dedicated page in my Wiki.

This is a weatherproof (or waterproof depending on the version) case for a RAK19003 based Meshtatic node. Since the RAK19003 includes a Li-ion charging circuit and solar panel input port, the cases have room for a 2000mAh Li-ion battery and some models have a hole for running wires from a solar panel.# Features The various versions have differing combinations of these features, indicated by the .stl name: ## Case USB - has a slot for accessing the USB-C port on the board (this is a power+data port) Solar - has a threaded hole to accept an M8 cable gland to run wires from a solar panel Mag - has a hole in the back of the case to fit an M3 heat-set insert for attaching a countersunk magnet to the case NoAntenna - has the antenna hole omitted in case you want to use a small embedded PCB antenna ## Lid Holes - has holes for M3 bolts for attaching the solar panel arm Oled - has a cutout for a 0.96" OLED display (this version is definitely not weatherproof)The Solar-Arm and Arm-Mount models are for attaching a pivoting solar panel directly to the lid of the case (simply using 20mm VHB tape), making an all-in-one solar-powered Metastatic node.# Waterproofing - The USB feature obviously can't be used as it's just an open hole in the case. For general weather resistance, the hole should be fine since it's on the bottom of the case. - The model TPU-Seal should be either printed out of TPU (or other flexible material) or cut out of some flexible gasket material. This provides a seal between the case and the lid. - The SMA antenna hole has a countersink on the inside of the case to use an o-ring seated between the rear hex of the SMA connector and the case. - The M8 threaded hole has a countersink to accept an o-ring on the cable gland, which, in combination with a round wire (as opposed to multiple wires) should create a water-tight seal for the solar power input. - The model TPU-Mag-Seal should be either printed out of TPU (or other flexible material) or cut out of some flexible gasket material. This provides a seal around the hole used to mount the magnet. Alternatively, a 16mm OD 1.5mm thick o-ring can be sandwiched in the groove in between the magnet and the case. - The Lid-Holes model includes indents to accept o-rings around the screws, providing a water-tight seal for the Arm-Mount. - Finally, the 3D prints themselves have to be waterproof, so using PETG, printing slower, hotter, and with less cooling, and using at least 3-4 perimeters is recommended.# Materials Note: The links are just example parts that will definitely fit, they're probably not the cheapest way to get the parts. Also, the links may die in the future if the listings are removed, in which case, you're on your own for finding the parts (that should be pretty easy though). ## Basic Case - 4x M3x6mm heat-set inserts [Amazon](https://www.amazon.com/gp/product/B087NBYF65) - 4x M3x8mm machine screw [Amazon](https://www.amazon.com/dp/B09TKSWCZR?th=1) - 4x M3 washer [Amazon](https://www.amazon.com/dp/B0B5GXMVRG?th=1) - 3x M2.5x4.5mm heat-set inserts [Amazon](https://www.amazon.com/dp/B07HKT5W7S?th=1) - 3x M2.5x8mm standoffs [Amazon](https://www.amazon.com/dp/B08F1YJX2Z?th=1) - 3x M2.5x3mm machine screws (I used the ones that come with the RAK19003, but any that are 3mm to 8mm long should work) - 1x SMA to U.FL 5cm cable [Amazon](https://www.amazon.com/dp/B01AJQ33Y4) (you can use longer, but it will get messy having extra cable in the case) - 1x 5mm o-ring [Amazon](https://www.amazon.com/dp/B01N75JL0F) (I used the o-rings that people buy for keyboard modding because they're extra soft and very cheap) - 1x SMA LoRa antenna [Amazon](https://www.amazon.com/dp/B095JTW6XM) (link is 915MHz for North America use) - 1x 2000mAh Li-ion battery [Amazon](https://www.amazon.com/gp/product/B07TVDQ251) (any battery will work as long as it's less than or equal to 46x44x9mm) - 1x RAK19003 Mini Base Board [rakwireless](https://store.rakwireless.com/products/wisblock-base-board-rak19003?m=5&h=wisblock-base) - 1x RAK4631 (nRF52840) or RAK113100 (RP2040) Core Module [rakwireless-RAK4631](https://store.rakwireless.com/products/rak4631-lpwan-node?m=5&h=wisblock-core&variant=37505443856582) [rakwireless-RAK113100](https://store.rakwireless.com/products/rak11310-wisblock-lpwan-module?m=5&h=wisblock-core&variant=40830755602630)## Magnet Add-on - 1x M3x6mm heat-set inserts [Amazon](https://www.amazon.com/gp/product/B087NBYF65) - 1x M3x10mm countersunk machine screw [Amazon](https://www.amazon.com/dp/B07DWVDDWC) - 1x countersunk magnet [Amazon](https://www.amazon.com/gp/product/B0C7M4LSBJ) - 1x 16x1.5mm o-ring [Amazon](https://www.amazon.com/dp/B07D9NSQJT?th=1)## Solar Add-on - 1x M8 nylon cable gland [Amazon](https://www.amazon.com/dp/B01MZXMWMR/) (I may try to modify the case in the future to support the much more common M12 cable glands) - 1x 5V solar panel [Amazon](https://www.amazon.com/dp/B0BJPWGM4D) For solar arm assembly: - 2x M3x8mm countersunk machine screws [Amazon](https://www.amazon.com/dp/B08HNDWFT8) - 2x M3x6mm heat-set inserts [Amazon](https://www.amazon.com/gp/product/B087NBYF65) - 1x M3 nylon lock nut [Amazon](https://www.amazon.com/dp/B075ZZW7VL) - 1x M3x25mm machine screw [Amazon](https://www.amazon.com/dp/B08R8J3175) - 1 piece of VHB tape for mounting solar panel [Amazon](https://www.amazon.com/dp/B01BU7038A) (or you could use glue)## Printed Parts ### Basic Case - 1x case variant (any of the cases are compatible with any of the lids) - 1x lid variant - 1x TPU-Seal (the .dxf file is provided in case you'd rather cut this out of something) ### Magnet Feature - 1x TPU-Mag-Seal (.dxf file is provided here as well) - case variant must include the Mag keyword in the file name ### Solar Panel Mount Feature - 1x Lid-Holes lid - 1x Arm-Mount - 1x Solar-Arm# Other Notes - None of the models need support. - The M8 threads on the Solar variants of the case don't come out super clean, so running an M8 tap through them is recommended. - I've provided the standalone STEP files for the basic lid and basic case models in case you want to modify them. I've also provided the STEP file for the whole set, which won't be a clean to work with, but should make adjusting tolerances much easier. - The cases all have passages on the back to allow them to be cleanly zip-tied to a post or something.# Planned Upgrades/Changes - I plan to make versions of all the cases that don't use heat-set inserts, instead having the screws bite into the plastic directly. This would be less strong and would wear out if threaded in and out multiple times, but should be simpler to make. - I might try to remove the M2.5 standoffs as well, replacing them with built-in stands. - I might try to adjust the Solar variants to accept the more common M12 cable glands instead of the M8 that they currently use.Feel free to modify these models however you want, I added the CAD files to make that easier. Also, I don't care if anyone want to take these models and sell them, I don't honestly think they're worth selling, but if you do want to sell them, just leave a link back to this page somewhere in your listing.
