RETRACTABLE ERASER HOLDER

This is a super retractable eraser holder with a cap. It is suitable for erasers up to 21 mm wide and 10 mm thick. However, you can adjust it using grips.

Glue is required to stick the 2 parts of the box together.

I hope you like this model!

Thank you in advance for your support, whether by simply liking this post, downloading the pattern or even subscribing to my account. Your participation would be greatly appreciated!

Here are the print settings I've patiently tested, researched and approved.

It's also worth mentioning that the complete model can be printed in less than 5 hours (in my experience) by following the settings I'll describe in the next section.

Personally, I use the Ultimaker Cura software, mainly keeping the standard settings, and print the model using PLA.

However, there are some variations in parameters between the different parts. For example, the sliding part requires tree-type supports to optimize printing, and a concentric top/bottom pattern. It is possible to add a spring to the quill of the sliding part to enhance the system, but this is not necessarily necessary.

These parameters have been optimized to achieve the best results in terms of print quality and strength. Feel free to adjust these values slightly to suit your 3D printer and personal preferences.
