Este é o repositório para a Graber i3: https://github.com/sgraber/Graber [Arquivos DXF e SketchUp disponíveis]
O design do Graber i3 é especialmente adequado para construí-lo com um cortador a laser ou até mesmo com uma simples máquina de corte CNC, como a Shapeoko. Ele deriva do design original do Prusa i3 e substitui todas as peças impressas em 3D por peças totalmente em madeira ou acrílico.
Volume de impressão: 200 x 200 x 200 mm
Lista de Materiais
This list may be incomplete!
The metric figures below are meant to be equivalent to their imperial counterpart - they might not be an exact fit.
M3 nuts will be to small for the provided slots (thus the strikethrough); M5 nuts would be wide enough, but the screw holes only have a diameter of 3.5mm.
One possible solution is to use M3 nuts+M3 washers. Find some M3 washers that have an outer diameter of 8mm, and use one washer per screw to make it a secure fit.
If you are laser-cutting the wooden pieces yourself, you will need two 810 x 460mm pieces of 6mm thick MDF.
