The kit
Round One. Two ways to get it.
One closed loop on one plate: the marble climbs 410 mm in the lift, runs over 8 m of track through a switch, a seesaw, an impact row and two brakes, and arrives back at the lift. Round and round.

Counts are the Round One run as simulated. They change where test series 1 says so.
Tier 1
Round One Kit
The whole run, ready to slot together. Every part printed and cut, motor, controller and marbles included, the plan of the run on paper.
- All parts listed above, printed in PLA and cut in MDF and acrylic
- Lift with motor, driver and controller, flashed
- 15 glass marbles
- Build guide and the run plan
For people who want to build and play and have no printer, or no time.
Tier 2
Round One Files
Every file. Your printer, your laser. The same parts as data: 3MF for the printer, DXF for the laser, firmware for the controller, the same guide.
- 3MF files, oriented and ready to slice, print times listed
- DXF files with cut and engrave layers, kerf already applied
- Arduino firmware for the lift
- Build guide, run plan, bought-parts list
Licence: for your own use. Print and build as many as you like for yourself, no resale or sharing of the files.
Price and timing
The kit is in development. Test series 1 on real printers and lasers runs now; when its numbers are in, the parts get their final fits and the price is set. The waitlist hears first, and nobody pays before that.
