	Here is an alternative to the Tooth Assembly. I removed the bottom attachment part. The total height is 1 inch the total length of the teeth is 4 inches. The teeth are meant to be welded on to the attachment plate. Easy. Simple. Durable. Replaceable. Convenient. What's not to like?		Here is an alternative to the Tooth Assembly.

I am interested in prototyping your bucket via 3D print if you can generate the printing files for the 3D printing file generation step of [[OSE_Design_Sprint#Design_Process]]. See [[LifeTrac Development Matrix]] for the green rows to see general proccess of 3D printing file generation. </span>

	The Quick Attachment Insertion Plate is centered along the longitudinal axis with the Stick Mounting Plate. Joining can be performed by bolting with recessed holes so that the surfaces remain flush/flat. Welding may be attempted but the residual bead left behind at the welded joints may cause interference and hinder/prevent the assembly from being inserted into the Quick Attachment Envelope on the Bucket. I am a little concerned about the 90 degree turns on the Quick Attachment Insertion Plate. These would be stress concentration points and, unless filleted or chamfered, will result in fatigue cracks. If fatigue cracks were to result the Bucket would suddenly and unexpectedly become detached from the Stick. This would be dangerous. Thus fillets or chamfers are recommended. A possible alternative construction would be to separate the Quick Attachment Insertion Plate into two separate plates, one being 1/2 inch thick the other 1 inch thick; joined together by an adhesive/epoxy and bolt combination. The adhesive/epoxy would be insurance due to the significant amount of stress this component will see. The exterior edge of the Quick Attachment Insertion Plate that is to be initially inserted into the Quick Attachment Envelope on the Bucket may be rounded or tapered to facilitate alignment and insertion of the plate into the envelope.
