***** NEW VERSION 4.0 *****

This is a large modular electronics enclosure for 3D printers. It's big enough (depending on controller board size) to hold the controller board, a Raspberry Pi, and other electronics. It is not designed to hold the PSU. It is 170mm wide by 220mm long and 64mm tall (68mm with the printed feet). This enclosure can be placed next to your printer or underneath it. If you place it underneath your printer it will need to be raised up on some legs. There are many designs available on Thingiverse including mine here https://www.thingiverse.com/thing:3592374.

I originally made this enclosure for my Adimlab printer, but it is designed to hold many popular control boards and a Raspberry Pi (3B+ or 4). If you want a control board added just let me know. It's also big enough to hold other electronics, like buck converters and MOSFETs depending on which control board is installed.

***** Currently these boards will fit into the enclosure (more can be added): ***** 01. Adimlab OG Gantry (LCD Option) 02. BTT Manta E3EZ 03. BTT Octopus 04. BTT SKR 1.3, 1.4, and 1.4 Turbo - also SKR 2.0 05. BTT SKR 3.0 and SKR 3.0 EZ 06. BTT SKR CR-6 v1.0 07. BTT SKR E3 TURBO 08. BTT SKR E3 Mini - Series 09. BTT SKR Pro 10. Duet Maestro 11. MKS Gen L 12. MKS Robin Lite 13. MKS Robin Nano Series (LCD Option) 14. MKS SBASE 15. MKS SGen L 16. MKS SKIPR

Most controller boards will have USB/SD ports on the front of the enclosure, but a few of the larger boards have ports on the left side. This is to enable room for the placement of wiring, particularly the power wires. If you would like to have a different configuration let me know. Some boards can be configured for different sides, but the larger boards are pretty much set as they are.

For each board, find and print the box side panel(s) and the other parts specifically listed for that board. For the other side panels of the box use the Box_Side_AA files.

Each board has a mounting standoff. All the controller board standoffs have been standardized for thickness and height. There are a couple of exceptions due to very unique circumstances. Most standoffs are symmetrical, but not all. Some have slots to help with screw placement and some are directional. Look for either 3 dots or an arrow. The side with the dots or arrow will go towards the front of the box.

Recommend the following procedure for the standoffs. Place the board loosely on the standoff in the box and line up the board to the USB/SD opening. Mark the standoff position on the bottom of the enclosure. Take the board out then line up the standoff where marked and screw it down using the mounting holes on the standoff (use at least 2 screws).

There are 3 different LCD options at this time. For the Adimlab printers, there is an option to attach the stock LCD screens into a housing on the front. There is also an MKS TFT35 LCD option for the MKS Nano boards. The original thing file for the panel is https://www.thingiverse.com/thing:2993069. I have included and renamed the original files without remixing them to fit the enclosure naming convention. Last, there is a BTT TFT35 housing.

The cooling fan opening on the lid is sized for a 120mm fan. If the board is too tall with drivers you can mount the fan on top (keep in mind the total height). I recommend using a 12v 120mm x 15mm fan (use a buck converter for a 24v board). There is also an option for 80mm & 92mm fans. Other fan configurations can be added.

Hardware: Recommend to use self-tapping M3 screws. Attach the bottom to the corners with longer screws such as M3 x 16 for a nice tight fit. The lid can be attached with shorter screws.

Use self-tapping M3 screws to mount the boards to the standoffs M3 x 4 or M3 x 6 should work.

Use M3 self-tapping screws or use m3 screws & nuts to attach the standoffs, the SKR Pro side box, and the cooling fan.

If desired use some glue to stiffen up the enclosure during assembly and to help hold other parts in place as needed. For wire management, use the new tie strap towers or some other tie strap anchors available on Thingiverse.

This is the type of self-tapping screws recommended: https://www.amazon.com/Zinc-Plated-Tapping-Assortment-Drilling-Storage/dp/B07DLWSQD5/ref=sr_1_3?dchild=1&keywords=self+tapping+m3+screws&qid=1602278163&sr=8-3

I used some parametric resources here on Thingiverse to help create the box and the standoffs and I thank those designers for their excellent work.

Please post makes!

**** UPDATE: 5/1/2023 This is a large update to this enclosure. I'm calling it version 4.0! **** -The main change is a new "pegboard" bottom. This bottom is covered with a grid of holes. This means that rather than placing a new board in the enclosure and putting new holes in the bottom the board standoffs are customized to fit the bottom.

• All the controller board standoffs have been standardized for thickness and height. There are a couple of exceptions due to very unique circumstances. Most standoffs are symmetrical, but not all. Some have slots to help with screw placement and some are directional. Look for either 3 holes or an arrow. The side with the 3 holes or arrow will go towards the front of the box.
• Some of the box sides have been updated for either size standardization or because of the positioning of the standoff/board to allow alignment with the new bottom holes.
• I'm working on adding a few new boards in the coming months.
• Some of the standoffs for things other than control boards still need to be updated

*** UPDATE: 5/6/23 ***

• Added/updated new standoffs for the accessory boards like mosfet's and buck converters.
• Added a new dual internal 40mm fan mount and a new left side to mount triple 40mm fans. To go along with the new triple fans, a clean lid with no fan cutouts.
• A ZIP file with all of the STL's has also been included.

*** UPDATE: 5/7/23 ***

• Added 18mm, 32mm & 45mm tall zip tie towers.

*** UPDATE: 5/24/23 ***

• Updated the MKS TFT35 LCD option files and information. The BTT TFT35 will be updated next.
• Updated the description some

*** UPDATE: 5/27/23 ***

• Updated the BTT TFT 35 LCD housing and mount plate. Made the housing a little deeper to account for cables. Adjusted mount holes for new enclosure bottom.

*** UPDATE: 11/18/23 ***

• Added support for the BTT Manta E3EZ. There are 5 new files for this board. They are the board standoff and all 4 sides of the box. Four of the AA corners will need to be printed as the ports for the Raspberry Pi have been eliminated.

*** UPDATE 3/13/24 *** I have corrected not including the board standoff for the E3 Mini Series. It is not quite the same as the E3 Turbo. There is a new board standoff in the files named Standoff_Brd BTT SKR E3 Mini - Series.stl. Also note I have renamed all the boards on the board list above (added BTT and put in alphabetical order), for consistency.

*** UPDATE 6/4/24 *** I have added support for the BTT Octopus. It is a large board so the Raspberry Pi will not fit as it is now. I will look into flipping it upside down. There are only two specific files for the BTT Octopus. The board standoff is Standoff_Brd BTT Octopus and it can be installed in either direction. The box side for the front is Box_Sides_BTT_Octopus_FRONT.

*** UPDATE 7/2/24 *** Added a new box lid that will allow the Raspberry Pi to be mounted upside down on the back end of the box lid. The fan is moved forward to allow this. This should help with large boards or if anybody just wanted a different way to mount the Pi. It is especially good for the BTT Octopus board.

*** UPDATE 11/11/24 *** Added a mount plate for a BTT TFT50 V3 LCD. The mount plate is a remix of the bracket from this thing: https://www.thingiverse.com/thing:4785907/files You will need to print the TFT50_Cover.stl from it to have the complete assembly.
