Thank you so much for publishing this!
I have been visiting your site regularly to see if you’d had chance to publish the build log, whilst appreciating that you must be very busy with your day job. It really is very generous for you to share your hard work so others may build their own stencil printer.
This is an excellent project and I can’t wait to build my own!
Thanks again 🙂
Hi,
Thank you for start the build log 🙂 Could you post a BOM so we can start to order the materials?
Hi,
could you add the size of Aluminum Extrusion?
Thank you
Hey Jose, thanks for your comment. Added a new step and updated the extrusion size. Thank you!
Thanks for the updates!
Hi,
thank you for this awesome construction.
I’m printing all the stuff at the moment. But I couldn’t find the 3d model for ‘ Adapter D5 to M3x14’.
Is it really missing or is it a standard item that can be downloaded elsewhere?
Thank you very much for the work!
Want to build it!
Do you have plans to continue build log with upper frame description?
If you want, i can make report about my build of your design, when it will be finished.
Hello. Amazing work, build one now. Can you post your pcb holders stl to thingiverse pls.
Hello Admin,
the project is really helpful and I’m in the process of building this,
can you share the build log building the top frame as well
Are on your plans release the full documenation?
Hello Dengler,
Amazing job on building and sharing this very nice stencil printer! it’s looking really good!
Hopefully you have been using it yourself too 😀
I am trying to order the parts for the printer (already started some 3D printing), but I was wondering if you have any documentation on the top frame/stencil holder? It looks fairly similar to the bottom frame combined with the x-axis carriage but I do notice subtle changes here and there.
Thanks again, great work on the design!
Hi, thanks for this great project! The part “Adapter D5 to M3x14” is not available in the 3D files on Thingiverse. Could you please upload it? Thank you!
