So I created a quick yoyo model (using SideEffects Houdini) to see how heavy it would be printed with my new 3D resin printer. I designed it to be undersized: 40mm x 50mm, and each half came in under 10g as estimated by the Chitubox slicer software I use. Now, even if I add Duncan aluminum performance rings (5.3g each), OD side effects and a bearing (5.2g total), the whole thing would only weigh in at around 34g. I guess the only way to make a resin yoyo with a normal yoyo weight is to make _a really big one_. 🤢 ---

Do you have a picture of the drawing? Are the walls large enough? ---

You know, the walls are most likely not remotely thick enough. But I have a sneaking suspicion that in order for it to have decent weight, the body would have to be an entirely solid bell. That means effectively zero weight distribution. ---

Resin seams to be way lighter then PLA the model above I posted ticks in at 29gram with an Radius of 5cm ---

The weight rings will add some good distro regardless. To get the body weight up though you’ll need the walls to be 4-5mm thick, and use 100% infill. I sketched up a thing: ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/4/2/b/42b4cedd82629027602718654bf2090188984d88.png) This is with 1.1g/cm^3 density, it ended up around 49.5g with all the parts. I’m more concerned about the outer rim above the weight ring - AFAIK the weight rings have an outer diameter of 48mm (radius 24mm) so the plastic surrounding it will be only 1mm thick, which is not enough. Probably need at least 3mm thickness there, which bumps your overall diameter up to 54mm. To be fair, the Butterfly XT is around 56mm in diameter, and a freehand is like 58. ---

That’s an excellent point about the size of the performance rings. Talk about having a total _duh!_ moment… ---

Thanks for the kind words. That drives me to make cooler stuff. I need to do some mod to fit in the side effects then I can share a gcode or whatever ur printer eats. ---

Yes it takes some iterations :wink: I did 5. I would suggest to just print the seat else it is really annoying after 4h print time. I also did this kind of complicated shape for it but it does not work very well I would suggest to make it simple. I will post a suggestion. ---

Thank you. I do actually have something similar to this printed, but the hole came out too small. I sanded it down to make it a bit bigger and the side effects can be added/removed. This new design uses a slightly larger ID for that section. I am not sure how it would turn out on a resin printer, though. Side effects are not really ideal for this, anyhow. Cabal guts would be much better. Simpler to design for, too. > [@hobbygod](#): > > this one looks like it would be fun. kinda reminds me of the spinworthy i have. The shape is definitely inspired by the Harbinger.
