I know
@Nefar is a 3d printer guy, he's done some grow tent accessory related prints
Yep — main printer is a
Creality K2 Plus, plus a few older ones kicking around. Printer tech moves fast. I've also put
Micro Swiss on all of them. I've had a noticeably better time with them than the stock setups — fewer clogs, more consistent results. Worth the money in my experience.
There's a lot you can print for the tent.
Filament: In the tent I use PETG. PLA sags in the heat — I've had clips let go. PETG holds up. TPU is basically rubber, good for grommets or anything that needs to grip or seal. Carbon fiber is strong but still a bit flexible, nice for clips. ABS, ASA and nylon off gas while printing, so keep those out of a bedroom or office unless you've got real airflow.
A few things that took me too long to learn:
Walls, not infill. When a clip breaks it splits at the outside edge, not through the middle. Going from 2 walls to 4 does far more for strength than cranking infill to 50%, and it uses less filament and prints faster. Single most useful setting nobody tells you about.
Wash the bed with dish soap, not alcohol. Everyone tells you to wipe the plate with isopropyl. A drop of Dawn and warm water in the sink, rinse, dry, and you get proper adhesion back. Save the IPA for a quick wipe between prints; give it a real wash when things start lifting.
Get a filament dryer. Humidity wrecks filament, PETG and TPU especially — stringing, weak layers, popping and hissing mid-print. It's the thing people skip and then spend a month blaming the printer. Pla if you bend over onto itself it will snap when wet.
If you want a look at the artistic side,
HueForge turns a photo into a layered colour print. You'll burn filament on the swaps but they look great. Software's at
https://shop.thehueforge.com and there's a big gallery of finished ones with files here:

What I actually print for the tent
Trellis net clips + pole connectors — by Wile E. 3D
https://makerworld.com/en/models/494702-grow-tent-trellis-net-connectors
16/18/19/22mm so it fits whatever poles you've got, plus a PVC version. This is the thing I print more than anything else. I run them thicker and slower than stock — standard thickness will eventually split at the seam once the canopy fills in and everything's pulling on the net.
Pole clamps for cable management — by TheMakersWorkbench
https://www.printables.com/model/171266-grow-tent-pole-clamps-for-wire-organization-gopro-
Ten different clamps in the one pack, 16mm and 22mm. Single cable, a 3-cable one, a heavier one for light and fan power cords, a trellis netting hook, and a GoPro mount. Gets all your cords up off the floor and onto the frame instead of running everywhere. Comes with the editable design files too, not just STLs.
Stackable crates — by Polymeria
https://www.crealitycloud.com/model-detail/661dd0435fb511ebaca83cbc
Printed a pile of these and they hold all my nutrient bags. They stack, so the shelf stops being a pile. One of my most-used prints and it isn't even grow-specific.
Light traps for passive intakes — four sizes, threaded
https://www.printables.com/model/928030-80-100-125-150-mm-light-trap-for-grow-tent-update
Printed the 100mm (4") and the 150mm (6"). These are for the round intake/exhaust ports, not the rectangular flap vents. I cut one shorter to fit a basement window too. Worth checking your tent with a flashlight from outside once it's sealed up — you find leaks you didn't know you had.
Bag clips — Bag Clip V2, by fifindr
https://makerworld.com/en/models/1984506-bag-clip-v2
Nutrient bags are the worst offenders — never resealable, the fold never holds, and you end up with clumped salts because moisture got in. A handful of these fixed a problem I'd just been living with. Print in PETG, the PLA ones go brittle and snap at the hinge.
4" duct volume damper
https://www.printables.com/model/640165-4in-4-inch-duct-valve-volume-damper
Dial airflow back without choking the fan down to where it's straining.
Seed starters — parametric, 9-pack of cups plus a basin
Search Printables for "parametric seed starter". I run the 9-cup plate and the 3x3 basin in PETG.
Plant / strain tags
https://www.printables.com/model/432278-customizable-plant-tag
Ended up drawing my own parametric version so I can just type a strain name in. It's in the zip.
THC molecule — line art wall piece
https://www.thingiverse.com/thing:5896504
Not grow gear, but people always like this one. Prints flat.
Other stuff worth a look
Swapped these off Thingiverse where I could — their ads are unbearable. Where the same designer cross-posted, that's the link. Where it's someone else making the same thing, I've said so.
Tent hardware
Light hanger 16mm, closed + open variants (different designer, same job):

https://www.printables.com/model/980013-16mm-grow-tent-hanger-open-variant
Pole connectors, T and straight, 16/18/22mm — Thingiverse only, nothing elsewhere does all three diameters:

Ducting
Magnetic vent connector (same designer, cross-posted):

2.5" flexible hose coupling (same designer, cross-posted):
https://www.printables.com/model/175819-25-flexible-hose-coupling-dust-collection
Duct Y splitter — parametric, any size and angle, does Y and T. Better than the fixed one I'd been using:
https://makerworld.com/en/models/2267982
Watering
Drip rings — I've tried a couple and honestly haven't had great luck with them yet. I end up drilling the holes out bigger than they come, and they're very dependent on the pot being dead level — off by a bit and one side gets everything. There are probably better designs out there and I'd take a recommendation if anyone has one.
GrowTek drip rings, on MakerWorld:
https://makerworld.com/en/models/58553
Drip irrigation ring, 100 and 120mm — this one at least ships OpenSCAD source so you can make the holes bigger properly instead of drilling them after:
https://www.printables.com/model/103003-drip-irrigation-ring
Plant pot riser, parametric:
https://www.printables.com/model/1263840-plant-pot-riser-parametric
Dual input drip ring — Thingiverse only. Two inlets is the whole point, run two pumps so one failing doesn't cost you the grow:
https://www.thingiverse.com/thing:4886191
Two I drew myself
Tent-to-tent connector tube. 12" long, sized for the 4" top port on an AC Infinity 2x2x4. Run two tents together.
strain tags. Open the .scad, type your strain name, hit F6, export. Prints flat, no supports, 5-7 minutes each.
Both in the zip as .stl (just print it) and .scad (the editable source). The .scad is the useful one — that's OpenSCAD, free at
https://openscad.org, and the file is just the model as plain text with the dimensions at the top:
Code:
length = 305; // tube length (mm)
od = 102; // outside diameter
Change a number, export. So if your port is 6" instead of 4" you edit one line instead of hunting for a different model. Same for the tags you type your own.
