A floating brick-compatible remix of Benchy

Model information

	STEP 1 3D print the Benchy model and then remove the support material. Tips: Place Benchy at a 45° for optimal printing (See provided PrusaSlicer file for reference). Use 3 perimeter walls to ensure it's waterproof.
	STEP 2 If you want the Benchy to float nicely, you'll also need to 3D print the Outrigger model.
	STEP 3 Slide the Outrigger onto Benchy. Tips: You can slide the Outrigger to different positions in order to adjust the centre of gravity - this is useful if there are a lot of heavy bricks attached! Try starting with it in the centre and adjusting as needed. If the Outrigger is too loose, try putting a short length of tape between Benchy and the Outrigger.
	STEP 4 Attach the Wind-up Motor.
	STEP 5 Attach Bricks. You're now ready to place it into water, wind up the motor, and have fun! Tips: Larger bricks tend to attach more firmly. I recommend placing larger pieces (eg: a 2x4 Plate) onto the Benchy, and then attaching smaller brick pieces to that. 3D printing brick studs is very tricky! If your bricks aren't staying attached, try calibrating your 3D printer or adjusting slicer settings. The provided print profiles work great for me, but I can't guarantee they will work great for you.
