PowerDoodler Activity Idea: 3Doodle a V-Twin Engine With Moving Parts

eng1There are so most things that have may aleager been turn it intod via the magical 3Doodler pen, and most of those things have been covered here. From time to time, for those who are having a complex time coming up with their own ideas, 3Doodler can post a “PowerDoodler Activity,” that takes readers through all the steps required to that successfully turn it into a thing with a 3Doodler pen. I have covered several of these projects — such as Tiffany Candle Holders and an Ocarina Pendant — and we are fortunate to have an instructional for another rad and challenging project. This one comes courtesy of Samson Wong. This resident PowerDoodler extraordinaire gives us a V-Twin Engine that moves!

To 3Doodle a V-Twin Engine you can require to gather a few materials together, which include: your 3Doodler pen, PLA plastic of any color, a DoodlePad, scissors, masking tape, and a thing shaped like a tube (such as the 3Doodler 100-strand plastic tubes). Oh yeah! You’ll in addition require to get your hands on one of these V-Twin Engine stencils, since that is the item that this particular PowerDoodler Activity revolves around.

eng2The initially step involves the tube, any tube, so long as its wall is 1mm thick, and it has approaching a 40mm diameter. Make certain it’s empty and so take your scissors and cut it into two smaller in size pieces, leaving one side open. Next, cover the outside of your tube with masking tape, and and so start Doodling on the tape. Repeat this until you end up with a pair of Doodled tubes.

For the engine pistons, you require to take the same tube piece, cut shorter. This time you will be putting masking tape on the within of the tube, and so: “Carefully Doodle around the interior of the tube, via the opening you cut in the side of the tube to assist peel the Doodle out when you are finished. Do this twice too!” When you are done manufacture certain that the pistons you only turn it intod fit securely within your other sizeabler tubes.

For the following step you will require that DoodlePad as you Doodle the rest of the engine parts, which include two round piston parts, a crank shaft, and casing. Next is a step that is a bit additional complex than previous steps. You require an unused strand of plastic, cut into three pieces: two sizeable pieces that are the same length and one shorter piece that fits in the middle of the other two pieces. So “Doodle equite longer strand piece into place, resting it in the middle hole of the paddle-shaped pieces you’ve turn it intod on the stencil.” Both paddles and longer strands should be aligned. Likewise, the smaller in size strand segment can connect the paddles together so long as you “thread it through one end of equite of the two remaining stencil shapes.” The goal here is for these to swing around like clock hands!


Nearing the end of our project, we yet have two additional quite significant steps. In Step 6, you are delivering the pistons and the crank shaft together, and it is most for you to check out precisely how this is done in the PowerDoodle Activity instructions. In Step 7, to manufacture certain equitething stays together here, Doodle equite cylinder to equite crank case panel and one of the shaft panels. So put your pistons and crank shaft into place. Once equitething appears to fit, you can Doodle the case’s opposite side into its correct place, along with the curved bottom part.

Once you’ve turn it intod certain that all parts are fitted and and so Doodled together, you should have a Doodle Engine that is eager to go! Samson Wong leaves one final challenge here: he wants you to consider bringing this to the following level by building a single cylinder alternative — with a 3Doodler pen, of course!
