<ul><li>Update 2023_11_15: added links to finger tracks XL for anyone struggling to get the print to work. </li><li>Update 2023_11_13: Updated files to chamfer some additional corners on the tread to feel nicer. </li><li>Update 2023_11_10: Updated models and print profile. Model is optimized to print better and the track will be much more reliably free running. </li></ul>&nbsp;Everyone needs some tracks to drive around with their fingers!This is a very satisfying and fun fidget, and also my first print in place model :) &nbsp;When first printed each track joint may take a tiny bit of force to free up; after that the tracks should run freely with little effort. &nbsp;To remove track:If it continues to be difficult to run, or has a sticky spot, you may have to remove the track to completely free up.This also makes for an easy multi-color model; print in two colors and swap tracks! (Don't risk this if your material doesn't have good layer adhesion like some matte or silk PLAs, you will break the track pegs.)&nbsp;To remove the track, hold with the connected side of the track body down, and with your fingers apply pressure on the wheel hubs to bend slightly inwards. This should provide enough clearance that the track can easily be removed. Replacing the track is slightly more difficult but follow the same basic strategy of flexing the track body. &nbsp;<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/370935/2023-11-13_dd9789575054a8.gif"></figure>&nbsp;PrintingThe model is made to work with and 0.4mm nozzle and 0.2mm layer height. If you use a larger layer height some gaps will be fused together by the slicer.&nbsp;If you are having trouble with your first print try a different filament, and please start with something simple like a plain PLA. Some specialty colors like silks mainly and some mattes lack the strength for this design to work well. Also, I strongly recommend printing In PLA; PETG tends to be hard to print things with small gaps without stringing or blobbing. Not that it's not possible, but you will probably have better luck with PLA, and no reason really to print in something more fancy. &nbsp;&nbsp;Print in the orientation shown below or as in the print profile. <figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/370935/2023-11-07_d1b42cc880c0e.png"></figure>&nbsp;If you want to print several different colors, you can fit 5 on the build plate in print by object mode. Then just print overnight or come back in ~10 hrs. I've uploaded this profile as well. <figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/370935/2023-11-10_af9cff3ff21ad.png"></figure>&nbsp;Related cool stuff!If you are having trouble with durability of the pins or tracks, or just not being able to get things to free up, check out the Finger Treads XL model. It has bigger pins and is a little more forgiving because of its larger size. It's big enough its not quite as good of a fidget, but still a very satisfying print in place model and fun to play with. &nbsp;Get it here: https://makerworld.com/en/models/65624#profileId-68957&nbsp;Size comparison below - XL version top. <figure class="image image_resized" style="width:32.59%;"><img src="https://makerworld.bblmw.com/makerworld/draft/370935/2023-11-15_b4cf6d1a056c8.jpg"></figure>&nbsp;&nbsp;&nbsp;If you have printed a bunch of these and need something to do with them, check out the Benchy-Dozer! https://makerworld.com/en/models/85433#profileId-91329<figure class="image image_resized" style="width:41.67%;"><img src="https://makerworld.bblmw.com/makerworld/draft/370935/2023-11-15_c16db6c5576808.jpg"></figure>&nbsp;
