Ulis spreadsheet driven loaf pan

[Ulicad]

Thanks to the many helpers from the forum who made a CAD representation of the loaf pan possible in the first place!

Each and every one of them is listed in the credits.

Hi everyone,
a loaf pan made by a layman is presented in its actual state - as is.
The history at the end of the post below is reflecting changes and releases.

The presented model is functionally mature and ready for practical use.
Very little effort and only limited experience in FreeCAD is needed for the creation of an individual loaf pan having exactly the capacity and dimensions required.

Two basic steps are neccessary to get a pan like this:

• Entering the pan measures and exporting

• Passing the 3D-model to a workshop

Jeno created and contributed this image,
all important aspects are nicely visible.



Full information about the loaf pan in its physical aspects is provided on these pages:

• In english language (planned for December)

• In deutscher Sprache

A collection of precreated sizes may be found here:

• english (planned for December)

• deutsch

For each size in the table, models also are offered for download (STEP exports) :

• english (planned for December)

• deutsch

(latest edit 24th Nov 23)
Known issues
- Sketch flipping occasionally, details coming asap
- Slight datum line deviation from valid position on top of pan. Without noticeable effect on model validity.

Status as of 17th Nov. 2023
Warning:

• Attached FreeCAD documents are NOT considered examples for preferred practices. Nor are they examples for nice UI-principles, mathematical or programmatic beauty. They are to be taken 'as is' for any versions released.

What the FreeCAD document is:

• It is one fairly simple sample for some features of what and how it can be done using FC. Given some effort only, it is not very difficult to follow its methods and paths for a user new to FC.

Thank you for taking the time to document your project. Can you tell us how much you'd have to pay for something like that at your local workshop?

Hi Max,
thank you, this exactly is hitting the main real world point to be looked into!

Regarding 'local':
I did not try to get prices locally since the handling costs (as a main cost factor!) presumably would be rather unfavourable compared to what may be called 'online' companies.
There was no time yet to clarify this generally. Like in so many other cases, 'the devil is in the detail'.

Two issues are to be considered:

• the maximal depth of the pan which can be manufactured using the existing equipment

• the granted precision in bending (bending radius, shortening factor)

Since the first prototype by design did not require a particular precision, it was manufactured by a german company (mainly online offers) for about EUR 45,-. For this prototype there were no particular price considerations.

The second prototype needed to satisfy both of the two issues from above and therefore was manufactured by a company supplying automotive parts as their main business. Under the label 'sample', I managed to get a price of EUR 80,- instead of EUR 160,- for a single piece in 2022.

There certanly is something more suiting to be found for this case and I am on it actually.

Best regards
Uli
