I’ve been designing 3D printable parts mainly around a simple idea: if a small household part breaks or something is missing, maybe we can just print a better replacement.

Here are three functional projects I’ve designed and actually used:

1. Bed Lift Handles – TPU Replacement

The original soft rubber-like handles on my double bed frame broke after several years of use.

I redesigned them in TPU for ACE / TPU 68D, with a reinforced geometry, comfortable grip and two-screw mounting.

Printed flat, without supports.

Print settings:
0.20 mm layer height
15–20+ walls
30–50% infill
8–10 top/bottom layers
TPU 68D

Model: Bed Lift Handles – TPU Replacement

2. Ultimate Speed 500533 Hydraulic Trolley Jack – TPU Handle Clips

A tiny part can make an otherwise perfectly functional tool annoying to use.

One of the original handle clips on my trolley jack broke, so instead of replacing the jack or hunting for a spare part, I measured it and designed a TPU replacement.

The clip installs directly onto the handle with no screws or additional hardware and can be printed without supports.

Designed specifically for the Ultimate Speed 500533 trolley jack.

3. IKEA HEMNES Clip-On Bedside Shelf

This one started with a simple problem: needing a small bedside shelf without drilling holes into the bed.

The solution is a clip-on mounting system for the IKEA HEMNES bed, designed for a 200 × 18 mm wooden shelf.

No drilling.
No screws into the bed.
No permanent modifications.

The printed parts use PETG and are designed to be easy to print and assemble.

What I like most about 3D printing isn't necessarily printing decorative objects.

It's being able to look at a broken or inconvenient part and think:

Can I redesign this and print a better solution?

These are three examples from my own home.

If you print any of them, I'd really appreciate seeing your Make/Print photos and feedback. I'm especially interested in how the TPU parts perform after long-term use.

What is the most annoying small household part you've ever wished you could just print?

After a few weeks of printing with the Kobra S1 Max, I ended up designing a full set of practical upgrades focused on airflow, maintenance, waste management, filament routing and overall usability.

Just functional improvements that actually make the machine nicer to live with.

Everything was designed around:

clean installation

printability without exotic settings

functional improvements first

OEM-style integration

Most parts are optimized for PLA/PETG/ASA/ABS where it actually matters thermally.

If anyone has ideas for additional S1 Max upgrades, I’m already prototyping more mods.

The machine is good stock. But like every 3D printer ever made… it gets significantly better after the community starts fixing things.

I designed two Dial Indicator Mount versions for the Anycubic Kobra S1 Max to make bed flatness inspection and first-layer calibration much more precise.

After fighting inconsistent first layers on larger prints, I realized that automatic leveling can hide a lot of mechanical issues.

So I started experimenting with physical verification using a dial indicator.

That led to these two versions:

V01

https://www.makeronline.com/en/model/Dial%20Indicator%20Mount%20for%20Anycubic%20Kobra%20S1%20Max/298381.html?trackModuleType=10

- mounts directly onto the original print head cover

- lightweight and simple

- fast installation

- no permanent modification

V02

https://www.makeronline.com/en/model/Dial%20Indicator%20Mount%20V02%20for%20Anycubic%20Kobra%20S1%20Max/298414.html?trackModuleType=10

- fully replaces the original print head cover

- integrated magnetic mounting system

- cleaner OEM-style integration

- improved rigidity and repeatability

- requires:

- 2x magnets 5x3 mm

- 2x magnets 4x3 mm

I mainly use them for:

- bed tramming

- bed flatness inspection

- first layer tuning

- gantry verification

- diagnosing print inconsistencies

Honestly, it changed how I calibrate the machine.

Mesh compensation is useful… but seeing the REAL mechanical state of the printer with a dial indicator is something else entirely.

I’m curious how other Kobra S1 Max owners handle calibration:

Do you fully trust automatic leveling, or do you also manually verify bed flatness?

I’ll add the MakerOnline links in the comments once the models are published.
