Is there anywhere that has just the guts already made in a 2d sketch, so that I don’t have to draw all of them? how did you start making each of those designs? because I saw that they look functional and I was wondering if you had to draw the tiny response area and shafts for each of them? ---

Here’s a downloadable Fusion360 file for the guts: [Fusion](https://a360.co/2Qjf2Qz) And here’s what it should look like in the editor: ![Fusion360](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/c/b/1/cb102ed4bcaadf9776e48e4c503eac740c177526.png) Right-click on any of the lines and “Edit Sketch” before you make changes, then “Finish Sketch” when you’re done. I’d recommend watching the series of videos by Zach Lerner to find out where these measurements come from.

Hey Mark, I think that sketch of the guts doesn’t really have a gap? And the width+depth of the bearing air groove and the response are the same? I haven’t done nearly as much designing as you have so you’re more of an expert than me, but thats just what I’m seeing, and I want to make sure we don’t accidentally mis-teach any newbies :joy: ---

These are the same guts I used for the diffraction, which has a 4.66mm gap. Here’s a sketch showing where the bearing fits (magenta), and the axle (black) and pads (green) ![1541353160071](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/8/7/d/87d254ab9552c97ad74f6457a8a7aa5be96e4042.png) ---

Some recent designs. Just spending lots of time practicing things. This one is an oversized (60mm x 47mm) bimetal with extreme rim-weight while totaling only 64.9g. Came about by the idea of “one throw” routines and what a yoyo that is designed specifically for them might look like. ![Yoyo_C_Bearing_2018-Nov-08_03-29-28PM-000_CustomizedView4133700027](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/b/3/d/b3d2ed4bd9e9e3cbf3e4b3700c440a78a9ec01c2.jpeg) ![Yoyo_C_Bearing_2018-Nov-08_03-29-36PM-000_CustomizedView14877549690](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/d/b/7/db763a4b255da7ac0aa4701a7956b43da8469ed9.jpeg) This is an undersized (52.6mm x 40mm) outer-ring bimetal where I was experimenting with D-sized bearings. 63.26g. Haven’t messed with the pads or gap yet, need to do some research on those. ![Yoyo_D_Bearing_2018-Nov-11_10-22-51PM-000_CustomizedView2447462817](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/6/3/1/6311df68b5cc0abfc1035c94cd24b146820e71d4.jpeg) ![Yoyo_D_Bearing_2018-Nov-11_10-22-43PM-000_CustomizedView11379608011](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/c/e/b/cebf69b11b764fef08fbf49eccc49e7bbfd89ca4.jpeg) And this is me getting jealous of the Edge Monster. 60mm wide.

One of the small touches I added for rendering was creating tiny fillets in the area where the two materials meet, which is more real-to-life and also looks better in the software. > [@knowledgeablepixels](#): > > also, your jealousy creation of the monster looks like the definition of the hourglass shape. call it the monsters nemesis or something lmao Oh man, I could round it out and make it look like an actual hourglass. ---

That’s fine, but I prefer a nice open catch zone without any response bumps. Response bumps absolutely murder the play feel of a yoyo. ---

There a more a few exceptions though, but it depends on how aggressive the bump is and the overall shape of the yoyo. The Onedrop Markmont Classic is one of those exceptions. ---
