BTT TFT50 Top Mount Designed for Voron V2.4/Trident

This is an assembly designed for use with the BTT TFT50 touch display and Raspberry Pi with Klipper Screen for mounting on top of a horizontal extrusion. Specifically I designed it for use with a default door configuration Voron V2.4, but it should work for a trident as well. The top panel of the printer must be in place to support the mount.

The Raspberry Pi mounts to the standoffs included on the BTT TFT50 and I used the included m2.5 screws to attach the pi to the TFT50 as well as mounting the TFT50 to the mounting plate. Other hardware: 

• 4x M3 heat set inserts for plastic (see drawing in photo for specifics)
• 6x M3x8mm SHCS for attaching the mounting plate to the extrusion and the top/bottom most holes in the Face Cover
• 2x M3x20mm SHCS for the “middle” holes in the Face Cover

The mounting plate will require support for the long 90 degree overhang and some of the bosses. The face cover may also require some supports for the screw bosses. None of the supported surfaces will be visible once assembled. By default the models are solid without any pattern included. I used a combination of print parameters to expose infill to use as a pattern. I have included 3MF files I saved in OrcaSlicer that should include the printing parameters for each part, but let me know if that is not the case. Using this method allows you to configure whatever pattern you would like based on the available infill patterns and adjusting density. The parameters I used for each part are as follows (parameters not listed can be considered normal to what you typically use):

• Mounting Plate - This can be printed as normal
• Face Cover - Bottom layers:0, Infill pattern:hexagon, infill density:22%
• Back Cover - Bottom layers:0, top layers:0, Infill pattern:hexagon, infill density:22%

The mounting plate must be installed first and prior to attaching the TFT50/RaspberryPi, though the Raspberry Pi can be attached to the TFT50 off of the printer. You will not be able to access the screws with the TFT50 in place. The standoffs on my TFT50 seemed to be barely attached from the factory, but don't freak out if one of them pops of during mounting. A dab of super glue works just fine for reattaching them. 

STEP files for each part are also included if you would like to make any modifications. The whole mount sort of depends on the thickness of the top panel on your printer, so the mounting plate may need to be tweaked. Mine is 3mm.
