Thank you to everyone who voted for my entry in the Instructables contest below. My entry finished near the top of over 3000 entries. I received a prize consisting of a T-Shirt and a voucher for 3D-Hubs along with some other little bits and pieces of Instructables merchandise. Hey everyone, I've entered a 3D printing contest on Instructables. Please vote for my Children's toy I designed from scratch for making on a 3D printer. Voting is easy just log into Instructables using your Facebook profile and click the vote link located at the top right of the page. Feel free to share this among your friends to help me win! My design has already been featured on the front page of Instructables. http://www.instructables.com/id/Digger-20-Childrens-Toy/ --------------------------------------------------------------------------- Updated 27/3/2016 see change list A larger more robust version of my original digger, with a few minor tweaks. only the bucket.STL requires supports testprint.STL is only for testing your ability to print a sphere, and not needed for the model. Change list: Added lego style assembly instructions with pictures Uniformed all peg holes as some were not the correct size Increased tolerance to 0.4mm for all connected parts Linkage Long no longer has its pegs incorporated into the model Reduced number of files by combining STL files. Print Settings Printer Brand: Printrbot Printer: Simple Black Rafts: No Supports: No Resolution: 0.1 Infill: 50% Notes: Only the bucket requires supports, the rest of the parts will print fine in their correct orientation. Singing a brim for the base will help prevent warping, and ensure adhesion to the print bed for the Pivot. Post-Printing Step 1 Once you have all your parts printed and cleaned up to your liking assembly is fairly straightforward. The parts should just press fit together but a small amount of super glue is recommended to give the model some strength. Starting with the base, take the three feet and press them into the three holes on the outriggers. Then take the ring and press it onto the top of the base. If needed, a drop of glue between the parts can be used to ensure they stay together. Step 2 Arrange your pegs ready for assembly. There are: 3x 12mm male and female. 4x 8mm male and female. 1x 8mm male 1x 11mm large male (no hole down the middle) If using super glue, having a number of bulldog clips at the ready will help clamp parts together while the glue sets. Step 3 Starting with the bucket, assemble the forward-boom to the bucket using 12mm male and female pegs. Step 4 Assemble Boom arm and 90 degree linkage with 8mm male peg Step 5 Assemble short linkage with 8mm pegs in the top hole and 12mm pegs in the bottom hole Step 6 Assemble long Linkage with 8mm pegs Step 7 Assemble bucket control with 8mm pegs Step 8 Attach the bucket and boom assembly to the Base-pivot using the 11mm large male peg (no hole down the middle). This will be a very tight fit. Step 9 Assemble the boom control using 8mm pegs at the bucket end and 12mm pegs at the base end. Step 10 Insert what you have assembled into the top of the base assembly Step 11 Manipulate all the joints to free them up. They may be stiff to begin with but with movement they will begin to move much easier.
