<h3>Have A BLAST Racing with Bellow Blasters!</h3><p>Straight from minds of <strong>Joshua R. Taylor</strong> and <strong>Dan the 3D Printing Dad</strong>,<strong> </strong>who were inspired by the brilliant toymakers of your childhood, comes a racing toy that you can print at home and race on any smooth, flat surface! Print enough for you and your friends and race each other! Or maybe:</p><ul><li>See who can get their vehicle closest to a target on the floor</li><li>Stack up plastic cups into a triangle and see who can knock the most down</li><li>Set up a paper jump and see who gets the most air</li></ul><p>The possibilities for fun are endless!</p><h3>Included 3MF Files for EASY Print Setup!</h3><p>Use the included 3MF files in PrusaSlicer to print out your parts with the suggested settings, including optimum support for the blaster nozzle. Just set the printer and GO!</p><h3>MAKE YOUR OWN DESIGNS!</h3><p>The included <strong>Bellow Blaster-Cutout.STL</strong> file makes it EASY to create your own Bellow Blaster vehicles in Tinkercad! Just follow these simple steps:</p><ol><li>Import your STL of choice (ideally, something with a large, flat base) and the Bellow Blaster-Cutout.STL using the <strong>Import</strong> button in Tinkercad:<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/ca570df2-e886-4c9c-9ce4-832d0c44c530/image.png#%7B%22uuid%22%3A%22d9a0c362-a2ee-42d7-916f-e7a48fad0e50%22%2C%22w%22%3A462%2C%22h%22%3A180%7D"><br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/37d79d82-3f0b-405c-99f1-8861e1160b90/image.png#%7B%22uuid%22%3A%22d11fe565-ac29-4374-8057-fec296205556%22%2C%22w%22%3A857%2C%22h%22%3A375%7D"></li><li>Orient and resize your imported object <strong>but not the cutout</strong> - make sure that the object is large enough to completely fit the cutout inside with room to spare on all sides. The cutout is 12mm x 12mm x 55mm:<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/7e9200fe-bccf-4cc4-9486-80d8ad2531c9/image.png#%7B%22uuid%22%3A%22b2027f5a-900f-4949-b7d6-e3a137e71c8f%22%2C%22w%22%3A1205%2C%22h%22%3A823%7D"></li><li>Raise the cutout 4mm up from the base of the Workplane.<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/ce3d954a-e8c6-4fd6-9caf-826845e74aa5/image.png#%7B%22uuid%22%3A%2219f7edd1-b502-4c52-8065-8b32007fa04c%22%2C%22w%22%3A951%2C%22h%22%3A455%7D"></li><li>Make the cutout a “Hole”<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/a12f105b-0679-498f-92f7-7a7477129f0c/image.png#%7B%22uuid%22%3A%2225344df3-3c29-46b2-825b-ef4f425249c1%22%2C%22w%22%3A561%2C%22h%22%3A308%7D"><br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/15b82017-9bc9-4e84-b79e-1b5e1dadeaab/image.png#%7B%22uuid%22%3A%22ec0ec722-87bf-4143-b17b-c9fce5d9329a%22%2C%22w%22%3A1440%2C%22h%22%3A757%7D"></li><li>Next, select both objects and type “L” to enter the align tool. Align the cutout so that it is centered side-to-side, flush with the back, making sure the cutout is still 4mm up from the base of your STL:<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/5d8b428e-16d5-47b2-8f7a-6e63a0b630f4/image.png#%7B%22uuid%22%3A%224248e775-b3d7-45fa-8e56-ea42641559e5%22%2C%22w%22%3A679%2C%22h%22%3A481%7D"></li><li>Making sure the two objects are still both selected, “Group” them together to cut the hole out of your object:<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/72a2b209-ca7b-4218-9d5a-ecda1865529c/image.png#%7B%22uuid%22%3A%22308beec3-e7ba-4cdb-bd93-3fc033a6dc09%22%2C%22w%22%3A417%2C%22h%22%3A225%7D"><br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/98e48b2e-be82-4de1-aece-fc65909f31f0/image.png#%7B%22uuid%22%3A%22849fb020-d5e2-4a80-9bca-d2a50973ddf6%22%2C%22w%22%3A1416%2C%22h%22%3A914%7D"></li><li>Now, all you need to do is “Export” your STL!<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/7a0af944-c342-484b-aac4-fb2b923517ee/image.png#%7B%22uuid%22%3A%227228f780-0e7e-42fe-9e8c-b2267add2a44%22%2C%22w%22%3A568%2C%22h%22%3A357%7D"></li><li><strong>NOTE:</strong> When orienting your newly-created STL in your slicer, I suggest placing the side with the hole against the build plate:<br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/e6875feb-7f9e-4965-80a0-0057d1b87fad/image.png#%7B%22uuid%22%3A%2287c4927a-3ac2-4ad5-99c8-0b21f9f8cc4c%22%2C%22w%22%3A1068%2C%22h%22%3A697%7D"><br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/6fd67d37-79b6-4ba8-aaa5-c30037df0b3d/image.png#%7B%22uuid%22%3A%22183e31e2-3662-4651-8593-bc81eb297513%22%2C%22w%22%3A502%2C%22h%22%3A321%7D"><br><img src="https://media.prusaprinters.org/media/prints/146539/rich_content/19bf9e29-ed3a-41f7-bee4-8c885f91b4fc/image.png#%7B%22uuid%22%3A%2242dee557-4758-48de-b115-f47a2753621f%22%2C%22w%22%3A562%2C%22h%22%3A505%7D"><br>&nbsp;</li></ol><h3>Tips for SUCCESS!</h3><p>The best TPU for the bellows is 95A Shore hardness - you'll find that not only is this a super-common hardness of TPU but that it is also relatively inexpensive and reasonably easy to print with. You can even have luck on a bowden extruder machine - just SLOW that speed down!</p><p>Looking for recommendations? I have tested Yoyi and Zyltech TPU on my Prusa MK3 and both work wonderfully.</p><p>When slicing vehicles you have created yourself, I suggest (when possible) orienting the print with the hole down, using zero or very low infill, and limiting shells to 1 for a lighter print that is more likely to glide on smooth surfaces. However, EXPERIMENT and you may discover even <i>better<strong> </strong></i>settings!</p><h3>SAFETY WARNING!</h3><p><strong>NEVER</strong> point or shoot the blaster at a human, animal, plant, or alien. In fact, just point away from anything living, OK? Point <strong>AWAY</strong> from your eyes and sensitive parts at <strong>ALL TIMES</strong>. You are responsible for yourself and any injuries you cause using this toy!</p>
