Sample Spool, ideal for 100g samples

Açıklama

Remix of the Proto-Pasta sample spool, with some enhancements Yes, yet another sample spool. I've tried many and liked the Proto-Pasta one best: Small inner diameter, to easily slip on the sample spools from my Proto-Pasta subscription. Large enough for 100g samples Works great with the roller-style spool holder I'm using, as well as spindle-based holders Parts lock together easily Prints with less than 100g of filament — yes, you can use your subscription sample to print a sample spool 🙂 But I saw a small number of opportunities for (admittedly minor) improvements: More attachment points for both the free and the free end of the filament Doesn't require that much thread to screw together securely. Added a small area to attach labels More “rounded” look. I tried to save even more material, but the outside frame became too wobbly. I redid the whole design in Fusion 360 but mark it as a remix of the Proto-Pasta design, to give proper credit for the inspiration. Print Instructions I strongly suggest using a layer height of 0.2mm or less. With 0.3mm, I had some issues with the thread overhangs. Can be easily fixed with an Xacto knife, but why bother. Also prints fine with a 0.6 mm nozzle. No supports needed. If you like what I'm doing… …consider buying me a coffee .
