What it is
A base that turns the head left and right and a neck that nods it up and down. It stays on the desk. Its head is the Gem head. The Mini v2's shield: wide across the cheeks, a narrow chin.
Its face, voice and moves run in the test room today. The program that runs them on the real ESP32-S3 chip is not built yet.
This is the Desk, turns and nods body with the Gem head. All 8 heads fit this body, and every pair is checked.
Three ways to get it
Built by 3D3D: from $315.14
3D3D buys the parts (at cost plus 15%), prints the pieces (by the gram), builds it and tests it. Build $50.00 and test $50.00, finishing at $25.00 an hour, only when a piece needs it. Shipping is on the invoice.
Printed kit: $72.12
The printed pieces, 155.6 g in all (PETG $0.11 a gram, TPU 95A $0.18 a gram, $5.00 setup, bed time per plate), with the parts list. You build it.
Build it yourself: free files
Print files for every piece, the parts list with links, the wiring and your design file. The bought parts come to $137.94 in whole packs.
You pay by Interac e-Transfer on an invoice the 3D3D team emails after it checks your design; there is no card checkout, and nothing is charged until you pay that invoice. Shipping is worked out from where it goes and added to the invoice.
Finishing is $0.00 on this bot: no piece needs supports taken off and it has no kit pieces to glue on.
