My favorite print recently have been duplo blocks that I reverse engineered and built back up in freecad for 3d printing. Here’s an overview of the pieces Ive modeled. Some were based off https://www.printables.com/model/137952-lego-duplo-compatible-building-block-2x2 originally and I used tinkercad to modify the model to create better clutch and fitment. Eventually I went full calipers on my kiddos duplos though and created a master sheet of dimensions that Ive used now in FreeCAD to remake everything. Toying with fitment and clutch has been a lot of fun as well as modifying the pieces for 3d printing.

In a very similar vein I spent a lot of time perfecting settings and orientations on this Lego Crocodile model https://www.printables.com/model/943591-lego-compatible-6026c01dat-animal-crocodile-comple/files

My kid absolutely love that I can print him out duplo pieces on demand.

As for practical this phone stand Ive really been loving https://makerworld.com/en/models/868130-herringbone-gear-phone-stand-pork3d-by-pork3d-com

Honorable mentions are the shelf I designed to hold my things along my desk and little figurines Ive been starting to toy with. Learning how to print things no designed to be 3d printed or modifying to print cleanly is really a fun challenge Ive found.

Thanks everyone for their shares, too! I def gonna print that hammer for a lighter touch than my engineering hammer.

I am going to plug my own project that I will complete in another revision when I can unpack my 3D printer when our 1st floor is completed in the renovation 😅

Other peoples’ that I like!

A VESA to microscope adapter for mounting a lighter microscope (I use a digital one) to a monitor arm to save space compared to the normal boom: https://www.printables.com/model/803413-amscope-eakins-microscope-vesamonitor-mount

All of Chris Borge’s stuff where he 3d prints useful simple machining tools and reinforces them with concrete (only a few on printables): https://www.printables.com/model/1237272-rock-solid-milling-machine-v09

The steam controller bumper repair. The brittle ABS they used broke 3 times for me (2 I sent back to steam and got a replacement), and I printed this in PETG and got my bumper back since the SC got discontinued and it has held up because petg is much lore flexible: https://www.printables.com/model/133723-steam-controller-bumper-repair

Bottle dryer. Use 3x daily for my stuff. https://www.printables.com/model/314913-bottle-dryer-system

Mario pipe pen cup. Stealth nerditry. https://www.printables.com/model/307980-mario-pipe-pen-holder

Grandma’s double sided filament clip. I’ve tested many clips. This fits my needs best. https://www.printables.com/model/581033-grandmas-double-sided-filament-clip

Thwack. Yes, it’s kind of a meme but for gentle taps it’s perfect. https://www.printables.com/model/46099-thwack

Dog poop bag holder. Works as described. My kids lose or break them far too often. Solution, print another. https://www.printables.com/model/167626-customizable-dog-poop-bag-holder

I’ll post some of mine to start. My favorites are mostly fun/decorative.

Fun

I’m a sucker for anything dinosaur. The original Flexi Rex was one of my first prints! I absolutely adore the art style of AndreasJoskaSutanto’s flexi dinos. My favorite is the Flexi Raptor

Most of the models are for paid members

Notable mention to this (free!) Flexi Dimetrodon by DirkvK that’s excellent too!

Decorative

I’ve been trying to fill the empty spaces on my walls. I printed a bunch of butterflies and bent the wings using a candle. I love how they’ve turned out! I’ll link to some of the ones I’ve found, in no specific order.

I’ve also been working on a bouquet of flowers, I’ll see if I can take a picture of it later to post.

All work done in FreeCad.

My favorite personally reverse engineered part

And a favorite design I use every day a holder for my loose tea strainer to catch draining water

The friendly articulated slug!

I really like the ones that are ultra-practical. Handles, curtain hangars, The Gatalog, adapters, pieces that fix broken things, etc.

But my ultimate favorite is the velocity stack i made for my car intake. lol
