Crates are great. They're even better if they're miniature, collapsible and stackable! This is a simple print that goes together without any hardware and can hold all of your little bits and pieces on your desk or workbench.

**Print Settings**
Nothing fancy here. 0.2 mm layer height and no supports required. If the parts are not snap fitting, try the sides with reduced tolerances.

This is a holder for your keys (or anything else that you might misplace) featuring a double action mechanism for locking and unlocking the key ring in place as well as ejecting it. It’s 100% 3D printed with only double-sided tape or two screws required to mount it to a wall. Featuring 3 different keyring styles and variants that hold from 1 to 4 key rings. Colour code your print or add your own name or logo to the keyring design. This design is based on my [Seat Belt Buckle Desk Fidget Toy](https://thangs.com/electrosync/Seat-Belt-Buckle-Desk-Fidget-Toy-35206?manualModelView=true).

Seat belt buckles have a pretty satisfying mechanism, but it’s not a great idea to play with them on the road! Now you can 3D print your own fidget and desk toy to play with anytime that you want. The design features a double action mechanism for locking and unlocking the tongue in place as well as ejecting it. It’s 100% 3D printed with no other hardware required. Featuring ~20~ ~30~ 40 plus different tongue styles, you can rep your ride! Want a different style on your tongue? Edit your own or let me know what you want in the comments.

This model consists of a three piece torpedo that houses a 16 g CO2 cartridge and ballast holder. The launcher is built with a few bits of hardware and is used to puncture the CO2 canister and launch the torpedo underwater. 
_The torpedo won't harm anyone, but be cautious around the launcher (sharp object) and CO2 gas (high pressure and cold)._

_Update: I've also added alternative top and lower sections by request that are extended so that the torpedoes will float rather than sink (untested)._

Check out the [Build Video](https://youtu.be/VAyJWpTFGtY) for assembly instructions and to see how they perform.

**Print Settings**
- Print all parts in their original orientation.
- Torpedo parts: 0.2 mm layer height, 40% infill, no supports (rely on bridging)
- Torpedo - Ballast Holder: Print two of 
- Launcher - Housing: 0.2 mm layer height, 40% infill, supports (touching build plate and increase overhang angle to 80 degrees to avoid supports on outer threads, or use support blocker)
- Launcher - Nail Holder: 0.1 mm layer height (smoother action), 40% infill, supports
- Other launcher parts: 0.2 mm layer height, 40% infill, no supports 
Launcher - Spacers: Print if required to add preload to spring (two sizes to choose from)

**Hardware Required**
- 16 gram disposable CO2 cartridges 
- 1 x M3 x 20 mm machine screw
- 1 x M3 x 4 mm heatset insert
- 1 x 12.7 mm x 38.1 mm x 1.041 mm compression spring (or similar diameter and use spacers)
- 1 x 50 mm x 3.3 mm nail (concrete nails are good)
- Fishing sinkers for ballast (or anything else that you can stuff in the nose cone)

This is modelled on Collins Aerospace’s ACES 5, but it’s also very similar to the ACES II. Add this ejection seat handle to your workstation or battlestation for when you need to eject from the real or virtual world! Stick the sign up to warn those around you. The multi-part print features a display mount for your desk and a hardware mount for attaching it to your flight sim set-up. 
The handle is a press fit into the bracket. Some hardware is required to mount it to the display stand/hardware mount (see below).

Bracket - 0.2 mm layer height, supports
Handle – 0.2 mm layer height, no supports (I used adaptive layer height for a nice surface finish)
Display Stand – 0.2 mm layer height, supports

These spacers are used to offset the body posts on the Tamiya TT-02 RC Car. I needed a longer one, so I designed it and I've also included the stock size here as well.

**Print Settings**
- I printed these in resin with a standard profile in the orientation the files are provided in with no supports. 
- You could print these in FDM, but I haven't tried.


**Hardware Required**
- If you're using the longer spacer, you'll need longer screws that you probably already have lying around.

This is a tensile bench test rig made from mostly steel construction for testing tensile strength of whatever you can fit in it. I've tested it up to 1000 kg (the capacity of my scales) to test the breaking strength of metal 3D prints. When things break at these tensions, they can shoot off like bullets, so if you do have a go at building one of these, make sure to take appropriate safety measures. 

You can check out the [Build and Test Video](https://youtu.be/Vrq59w69Rwk) to see how it all works.

**Print Settings**
- A few bits and pieces printed in PLA+ and TPU - mainly for appearances.

**Hardware Required**
- The majority of steel is 50 mm x 50 mm x 2 mm
- For the pivot arm, I used some salvaged steel: 50 mm x 60 mm x 5 mm (this arm takes most of the force). 
- A barrel jack is used to apply force to the test rig.

These are the 3D printed parts that make up the automated water sampling carousel that fits to the [Modular Deck System](https://thangs.com/designer/electrosync/3d-model/Modular%20Deck%20System%20for%203D%20Printed%20RC%20Catamaran%20Utility%20Boat-44113?manualModelView=true) of my [RC Catamaran Utility Boat](https://thangs.com/mythangs/file/44098). It holds four 200 mm sample bottles and one of the spots on the carousel can be for a purge bottle (bottomless) that runs the pump back to the water body that you are sampling. Parts 2-6 are the core parts for the carousel. The other parts are for mounting the liquid level sensor and electronics cases - this will depend on your setup. It uses readily available hardware and electronics (more details and parts listed below). [This is the Build Video](https://youtu.be/Bp1Fw5bALzA)

**Print Settings**
- 0.2 mm layer height should work for everything except for the 90 tooth pulley that you may like to print at 0.12 mm or so. No supports are required.

**Hardware Required**
- 3 mm hardware for mounting the motor, pulley wheel and turntable bottom. 
- 6 mm bolt, nut and washer to mount the turntable top to the bottom of the motor electronics case lid
- 200 mm GT2 belt
- NEMA 17 stepper motor (pancake is better if you have it)
- 20 tooth GT2 pinion (stock on many 3D printers)
- 1 x 608 bearing for pulley wheel
- 3 mm heatset inserts for cases
- The quick release pins use R clips
