Mount your Quad Locked device on your squat rack, fridge, locker, or other random metal surface!

Takes four 7x3mm neodymium magnets, which will sit 1mm proud of the surface for maximum magnetting.

**NOTE:** _This is strong enough to hold  my Samsung Galaxy S10+ securely, BUT your mileage may vary depending on your phone, case, and whatever magnets you're using. Test carefully and at your own risk!_

Holes are sized to 7.1mm so tolerances are tight, make sure your flow calibration is dialled and consider printing outer perimeters first for accuracy. If it's snug then you can press-fit, otherwise drop in a dab of CA glue.

(v1 used 6mm magnets, too weak for my phone but it's there if you wanna try it)

I'm still tweaking the locking nubs for a more secure fit, but it works well enough to be used.

**My print settings:**
- **Line width:** 0.4mm
- **Layer Height:** 0.15mm
- **Top/Bottom Layers:** 6
- **Perimeters** 3
- **Infill:** 15% Gyroid


Quad Lock magnet mount

Mount your Quad Locked device on your squat rack, fridge, locker, or other random metal surface!

I designed this to string up Christmas decorations around our 10mm recessed ceiling borders but with a bit of tweaking you could use it pretty much anywhere you need to hang stuff that isn't too heavy.

**NOTES:**

* With a single cooling fan I got way better adhesion aligning the part perpendicular to the airflow.
* If you're only printing one then go slow, or make sure your minimum layer time allows for enough cooling between layers. Once I got the design nailed I just did a batch of 20 in one go.
* The included Fusion 360 file also includes an earlier version with more aggressive teeth that may grip better in some applications, not parametric but easy enough to adjust the sketch if you need to.

**MY PRINT SETTINGS:**
(Definitely some room for tweaking but this worked for me, approx. 4 minutes per hook)

* **Printer**: Ender 3 S1 Pro + Sonic Pad
* **Nozzle:** 0.4mm brass
* **Filament:** Creality PLA (black)
* **Temps:** 195° / 60°C
* **Speed:** 50mm/s
* **Line width:** 0.4mm
* **Layer height:** 0.2mm
* **Top/Bottom layers:** 2
* **Walls:** 2
* **Infill:** 40% Cubic
