TFT35-E3 case for Ender 5 Plus

thingiverse

Enclosure for BigTreeTech TFT35-E3 dual-mode screen, for replacing the standard display on the Ender 5 Plus. <b>Requires a total of nine M3 bolts.</b> M3 × 8 mm (or longer - up to 12 mm) <b>×7</b> – four for holding the TFT35-E3 board between the Back and Front (ensure that the Button is placed before closing the case), and three for securing the Mount to the Back (install Mount inside E5 Plus case, where old display was located). M3 × 8 mm (or longer - up to 20 mm) <b>×2</b> – for securing the Rear to the Back. Screw-holes have been left in the corners of the Back and Front, but should not be required. The four screws that sandwich the TFT35-E3 between the Back and Front should be sufficient. Pre-thread the M3 bolts to make final assembly easier. <b><i>Note: feedback from one person was that they needed to use a 102% multiplier to obtain a correct fit as it was too tight for their board at 100%. Please print the 'TFT35-E3_Front_rev2.stl' first and check for a good fit.</i></b> [Note added 2020-10-08.] <b><i>Note from feedback on the screen location: the screen is secured with an adhesive pad, and may not be perfectly aligned with the front bezel. Test fit the board, and then — carefully — remove and shift the screen if required. The other option is to fit the board, measure how far the window must be moved, then open the source in DesignSparkMechanical and move the window.</i></b> [Note added 2021-02-08.] <b><i>Note from feedback on the button: if the button seems too loose then you may upscale it in the slicer or from the DSM files — suggestion from one person was X 11.8 mm x Y 11.8 mm x Z 5.7 mm (I will add resized buttons as an option soon) — or shim it with some soft rubber or similar. Ensure that it won’t stick when depressed: it must be a ‘click’ then return operation.<i></b> [Note added 2021-02-08.] <b><i>Note from feedback on WiFi case: the WiFi module may be too tight in the cutout for it. I don’t have this, so sized from the drawings. I will update this part soon and enlarge the space.<i></b> [Note added 2021-02-08.] You will need to print the following: • TFT35-E3_Front_rev2.stl • TFT35-E3_Back_rev2.stl <i>or</i> TFT35-E3_Back_rev2_wifi.stl • TFT35-E3_Rear_rev2.stl • TFT35-E3_Mount_rev2.stl • TFT35-E3_Button_short.stl <i>or</i> TFT35-E3_Button_long.stl (The long button protrudes above the top of the front of the case. As this is for resetting the display, I made a short version that does not protrude, making it more difficult to accidentally depress.) Built in RS DesignSpark Mechanical, using the 'things' as mentioned in the remix section as inspiration and to check initial dimensions. Source files included for modifications. Photos show components for my use, without the WiFi opton. If you have the WiFi module, then you can print the 'TFT35-E3_Back_rev2_wifi.stl' variant. (Or customise from the DesignSpark Mechanical files). <i>Note that the 'TFT35-E3_Rear_rev2.stl' component should be able to be modified for ports to bring through USB and card connections from the printer mainboard. This will be updated if I do so when the BigTreeTech SKR 1.4 is installed in my Ender 5 Plus.</i> (Files have "rev2" present as my initial design was tidied up and reduced in size a little to produce this one. No earlier revision has been uploaded.) Updated 2020-08-12: slight changes to STLs – mainly additional chamfers to aid with threading bolts. Updated 2020-08-14 (again): photos of Rev2 parts included. Note TFT cable routing shown in last two photos, to avoid the screw boss. Changed minimum suggested bolt length for attaching Rear component to Back.
