New HP-41 Calculator Stand
I have designed a 3D Printed stand for my HP-41 that I would like to share with anyone who is interested. It works well for Classics and Pioneers as well, even a DM42 or DM41X.

Here is a link to the model on thingiverse:

Yes, thanks tw for creating and sharing this! A friend is making a couple for me now.

Looking at the recess for the pads, it appears to be sized for a 41, but the recess is clearly oversized for just that; which models did you use to define the sizing and geometry for the various calculator feet?

I wish that I could impress you with some sort of grand plan but I am afraid that the only explanation for the vertical size of the recesses is laziness. My biggest concern was to prevent the calculator from slipping from side to side. I should have gone in and refined the model before publishing it. It would not be too difficult to make it fit a pioneer by making the lower recesses just a bit wider and adding another upper recess to accommodate the long "monofoot" on the top.

Stay tuned...

Great news actually... this means the 2 being made now will become "rare, 1st generation models, only available for a limited time". You know how to please an obsessive collector. Smile

I imagine a 'SwissMicros Edition' version, that nicely accommodates the DM42/41X rubber feet would be popular as well....

OK, Bob, You've shamed me into it...
I am printing a test model now that is designed to accommodate 41's, Pioneers, and DM42/41X. New Model should be on thingiverse tomorrow.

Hopefully there's no shame involved at all... quite the opposite, you're the one doing the work and enriching the community by sharing it! Big Grin

The flexibility for this new one sounds great, I am looking forward to seeing it.

Thanks again.

Ok. The modified model is up on Thingiverse:
https://www.thingiverse.com/thing:4439055

It is a bit longer so as to accommodate the position of the DM42/DM41X Feet.
It has recesses to match the feet of an HP-41, 67, Classic, Pioneer, and DM42/DM41X. I also modified it to print without supports.

Nice!! Big Grin

Obviously much more flexible, the revised design of the lightening holes on the sides is more rakish, giving it a slightly meaner, more serious look, an improvement I appreciate.

I'm not real familiar with the 3D design and mfg. process; how can the portions suspended over air start to print with no integral supports?

I'll leave some feedback once I have some in use, but of course I can thank you now for this wonderful gift to the community.

A final question: AZGN ?

Thanks!
