Frequently asked questions

Answers on design, drawings and ordering.

Do I need special knowledge?: No. Pick a profile and grooves, adjust numbers, and you get a machinable design. No difficult tools — machining constraints are checked automatically.
Can it really be machined from the drawing?: Yes. Dimensions are JIS-compliant and toolpath coordinates are output, aiming for accuracy a lathe or mill can run directly.
What grooves can I make?: Ring grooves, shark cuts, spirals (lathe threading), axial grooves (ball/V tools, swept bottoms), dots and polygon sections.
Does it work on mobile?: Yes. Phones use a vertical layout, PCs keep a side input dock — you can design on either.
Who owns my design data?: You do. Showcasing your work requires your consent and credit; we never publish it without permission.
How are factories chosen?: We match among partner factories by the machining and finishing they support. Factories without colour can receive plain orders.
Can I add text or a logo?: Yes. You can engrave text on a free surface and choose the font and orientation. On the PRO plan you can also upload black-and-white logo images and engrave them (store several and pick one to place). If the barrel is full of grooves with no free space, engraving may not fit.
What’s the difference between PLAYER and PRO?: PLAYER is for individuals who want to design their own barrel and get drawings. PRO is for dart designers and brands: design straight to production specs, 80% faster drawings, multiple designer seats, design sharing with PLAYERs, and approval/production-request workflows.
