3D Printed Camping Gear: Tent Pegs, Clips, and Lantern Hooks

The 3D printed camping gear worth making is small, cheap to replace and not load-bearing: guy line tensioners, tent pegs for soft ground, replacement pack buckles, lantern hooks, cord organizers and gear clips. Print them in ASA for anything that stays outdoors, PETG for weekend use, and never print anything that would hurt someone if it snapped.

What's actually worth printing

Not everything. The 3D printing camping community has a tendency to print things that already exist in better form at the hardware store. A $3 aluminium carabiner beats any printed one. I've stopped printing solutions to problems that don't exist.

What IS worth printing: things that are custom-sized, things you lose constantly and need cheap replacements for, and things where commercial options are overpriced for what they are. Guy line tensioners cost $1–2 each from tent manufacturers. I can print a set of 12 for the same price in filament. Replacement buckles for a specific pack? $8 from the manufacturer, three weeks shipping. Printed one in 40 minutes.

Here is the honest scorecard from two seasons of printing camp kit. Times and weights are measured from my own prints at 0.2 mm layers on a 600 mm/s class machine; your slicer will land within about 20 % of these.

The best camping prints are small, functional, and not load-bearing. If your safety depends on it holding, don't print it. For everything else, the functional print ideas collection has more projects in this category.

Material choice for outdoor gear

Outdoor camping gear faces UV, temperature swings, moisture, and mechanical stress. CNC Kitchen's mechanical testing quantified the differences between the three common filaments for this kind of use:

ASA is the clear winner for anything that stays outdoors. Roughly three times PLA's impact resistance, holds shape up to 110°C, and resists UV for years. It needs a heated chamber to print without warping, but that's a one-time setup issue rather than a per-print one.

PETG works well for gear that sees intermittent outdoor use. Weekend camping trips where gear goes back in a bag between uses won't cause significant UV degradation. Filamentive's UV resistance comparison ranks material longevity for extended outdoor exposure.

PLA? It's fine for prototyping a design before printing in ASA. And for single-trip items where you don't care if they survive the return journey. I've printed PLA tent pegs as emergency spares knowing they'd be garbage by next season. For a broader material comparison, the complete filament guide covers all the mechanical and thermal properties, and the high-performance filament range is where the outdoor-rated materials live.

Garden and yard parts face the same UV and moisture problem for far longer than a weekend trip. UV resistance for trellis connectors and the best filament for garden hose guides under rain and UV both go deeper on how each material weathers.

Tent pegs: the honest assessment

Printed tent pegs are the most popular camping print. They're also the one where expectations need the most calibration.

A tent peg is a stake driven into the ground to anchor a tent or tarp, and its holding power comes from soil friction along the shaft plus resistance to being levered out. That is why profile matters more than material for a printed one.

In soft to medium soil — forest floor, sandy loam, established campsites — printed pegs work. The Y-beam profile provides the best holding power because it resists pull from all directions. Textured surfaces along the stake shaft improve soil friction. I printed a batch of Y-beam pegs in ASA at 35% infill with 4 walls and they've held my tarp through moderate wind without issue.

In hard-packed clay or rocky ground, plastic pegs snap. Period. The community workaround is a hybrid: a 10 mm coach screw driven with a cordless drill, with a printed handle sleeve over the head for extraction. You aren't hammering plastic into rock; you're driving a steel fastener and using the printed part only as a grip. That approach works where a solid printed peg simply doesn't.

Weight savings? Honestly minimal. An aluminium mini Y-stake weighs about 10 g. My printed ASA pegs weigh 8–15 g depending on design and infill. The advantage isn't weight. It's that I can print 20 replacements for about $3 in filament and stop caring when one is left in the ground.

Small accessories that earn their weight

Guy line tensioners

These are the one camping print I recommend without reservation. The Paracord Tensioner pack by guppyk on Thingiverse has six designs in two sizes — the small ones sized for roughly 2 mm cord, the larger for about 4 mm paracord. I printed them in glow-in-the-dark PLA so I stop tripping over guy lines at night. They weigh 3–5 g each, take 15 minutes to print, and work exactly as well as the $2 commercial versions.

Replacement buckles

Buckle on your pack broke? Measure the webbing width with callipers, find a parametric buckle model, set the slot to webbing width plus 0.4 mm, and print in PETG or ASA at 50 % infill. I've replaced three buckles this way: one on a dry bag, one on a pack hip belt, one on a stuff sack. Total cost in filament: about $0.30. Total quoted from the manufacturers: $24 plus shipping.

Lantern and gear hooks

S-hooks sized for paracord ridgelines, carabiner-style clips for hanging gear bags off a bear line, and lantern hooks that clip onto tent poles. Small, fast to print, and genuinely useful. I keep a set of six hooks in my camp kit and have never had one fail — because none of them carries more than a couple of kilograms.

Cord organizers

Wrap-around cleats for neatly storing guy lines and paracord lengths. Prevents the tangled mess that happens when you stuff loose cord into a bag. Print in PLA since these don't see mechanical stress or UV exposure while stored.

For a broader inventory of what other people carry, the Cloudline ultralight gear list is a good weight-conscious starting point. Whatever you print, pack it out again — printed plastic left at a site is litter, and Leave No Trace's seven principles apply to a broken tent peg exactly as they apply to anything else.

Two more small parts worth printing before a trip: custom GoPro mounts for cyclists, and for anyone whose hands tire quickly, ergonomic pruner handle aids designed for arthritis.

Print settings for outdoor strength

Outdoor parts need to survive being dropped, stepped on, and left in weather. Making prints stronger starts with settings:

• 4–5 walls (2–3 mm wall thickness). Walls matter more than infill for flexural strength.
• 35 % infill minimum. Triangular for maximum strength, gyroid for best strength-to-weight ratio.
• 0.2–0.3 mm layer height. Thicker layers bond well for load-bearing parts.
• Print temperature at the upper end of the filament spec. Better inter-layer fusion.
• ASA: 250 °C nozzle, 110 °C bed, 55–65 °C chamber. The Q2 holds a 65 °C actively heated chamber and lists at $499, which is the cheapest reliable route to ASA I know of.

Orientation matters more than any of those settings. Tent pegs should print vertically so layer lines wrap around the shaft. If layers stack horizontally along the peg length, a bending force will peel them apart — plastic printed this way is anisotropic, meaning it is markedly weaker across layers than along them. For hooks and clips, orient so the load pulls parallel to layers, not perpendicular.

If you want to know how long those settings will actually buy you, predicting the outdoor lifespan of 3D printed garden mounts turns the same variables — material, wall count, pigment, sun exposure — into a rough service-life estimate.

Safety notes

This needs saying clearly: 3D printed carabiners are not climbing equipment. They are not rated for fall arrest, belaying, rappelling, or any situation where a failure means someone falls. Real climbing carabiners are rated at 20–28 kN and tested to CE/UIAA standards. A printed carabiner has anisotropic layer bonds that can fail without warning. Use printed carabiners for hanging gear bags, attaching a water bottle to a pack, or organising camp kit. Nothing more.

General outdoor precautions: inspect printed parts for cracks before each trip. UV and temperature cycling cause material fatigue that is not always visible. Carry backup aluminium stakes. Don't leave PLA parts in a hot car on the drive to the trailhead — the cabin of a parked car can pass PLA's 60 °C softening point on a summer afternoon. And if you're printing gear for fishing lures, the same material durability principles apply.
