Looking for MORE upgrades for your enclosure?  Consider doing this one!

[CORRECTION - Oct 22, 2023]:  Thanks to @Pred and @Zhaya, who brought to my attention that the clearance features for the enclosure housing screws were “off” for the LEFT version for the Sheet Holder LHS and Sheet Holder Bottom LHS, because the location of the screw holes were NOT mirror image from right side to the left side as I originally thought (assumed). It's now been corrected and the correct files are uploaded.  All the internal parts fit both left and right versions.

If you've already printed your LEFT version, and want to correct the minor alignment issue, you'd only need to print the Sheet Holder.  The Sheet Holder Bottom only has a small notch for clearance that you may be able to do some quick rework with a file - it would save you from the time and material of a reprint.

[Updated Aug 28, 2023]:  Thanks to the helpful feedback from the make by @carlmmii_321665 I was able to fix a small issue with the notched clearance on the ejector button.  All other issues he mentioned was already found and corrected, but unfortunately he didn't see my updates before he printed his make. However, to be safe, I've re-uploaded all the models.

[Updated Aug 24, 2023]: A few hours after I published the models, I discovered that I had accidentally suppressed some features before I converted my files to .stl, without which would cause an interference with the enclosure screws.  The files are updated now and the effects are limited to all Sheet Holder and Sheet Holder Bottom parts, not the internal parts.  *** IMPORTANT ***  To be safe, please download the mentioned files again.

Inspired by the community's new energy from the release of the MK4 and the Original Prusa Enclosure, I took up this project of creating a new sheet holder that has a built-in sheet selector and (tilting) ejector, mounted to the side of the enclosure.

Accommodates all Prusa branded print sheets: 

1. Prusa Smooth
2. Prusa Textured
3. Prusa Satin
4. Prusa Nylon

***  Please Note: it doesn't actually EJECT the sheet, but rather, tilts the selected sheet upward and outward to make it easy to grab. ***

It mounts to the side of the Original Prusa Enclosure for easy access - 4 versions are shown here.  You can mix-and-match the triangular patterns to be on the top part or on the bottom, or both, or none.
 

Features: 

1. Mounts to the side of the enclosure, left or right, take yor  pick. 
2. The selector has an indexing feature so you know where to stop for each sheet.
3. Large button to push.
4. Easy to assemble.
5. Allows for storage of 6 sheets in a compact space.
6. Prints mostly without supports. The 2 parts that need supports has them already built into the model.

Left and Right side versions are provided:

1. Right side mounted - with triangular designs
2. Left side mounted - with triangular designs
3. Right side mounted - plain
4. Left side mounted - plain

** Added Oct 22, 2023: NOTE ** Left and Right side parts for the Sheet Holder and Sheet Holder Bottom are NOT mirror images of each other.  Don't try to mirror the parts yourself.

Assembly: 

Other items you'll need for assembly:

1. 6x M3x10 SHCS (socket head cap screw)
2. 1x M3x8 SHCS (to selector back rotation point)
3. 2x M3x12 SHCS (black) - use the spare screws from your enclosure kit
4. 1x M3x6 SHCS
5. 2x M3 Square Nut

Remove Built-in Supports:

Printing Recommendations:

1.  Print in the orientation provided in the .stl file (relative to print bed) - it is oriented for strength and dimensional accuracy.

2. Rotate model relative to Z axis to fit your printer. 

3. Since this is a relatively large model, the use of corner adhesion helpers AND 3-4mm brim are Highly Recommended to keep the Sheet Holder and Sheet Holder Bottom as straight as possible.

4. This model is a perfect use of PLA.

5. Prints with 0.4mm nozzle and 0.2mm layer thickness.

6. 2-3 vertical walls should be sufficient.

Happy Printing!
