The original Hori L2/R2 grip was only made for the PS Vita 2000. I took the 3D scans of the Hori grip by Wesk over on BitBuilt and modified them to fit the PS Vita 1000 without needing an adapter kit. I also decimated the high poly scans so they slice cleanly.

Since the base files are 3D scans rather than drawn CAD models, the geometry looks a bit unusual if you inspect the mesh closely. I’ve put a lot of work into modifying, cleaning up, and reinforcing parts of the grip so anyone can print it and put it together with just a few materials.

I have modified the triggers so they work with gravity, no wire or springs needed and the result is pretty effective. the smaller triggers are hollow and can be weighed down with two M5 bolts secured with glue, and the large triggers have a counterweight lever attached to them which I glued an M6 bolt to. The triggers activate the touchpad with conductive tape routed from the trigger to the pad, this works very well but conductive filament would be even better.

For the rear shell, I wanted the nice side of the print to be on the outside of the grip where my hands rest, that meant the internal side where the triggers sit had to be cleaned up by hand due to the extensive supports needed. The front half of the grip can be printed internal side up and minimal clean up is required. I lined the part where the vita sits with some fabric electric tape, this keeps the vita snug within the grip.

I added THUB on the rear shell for my own grip to add a bit of personalisation, I have left it blank for the final release.

Print settings I used with my ender 3 V1 and Ultimaker Cura:

• Standard quality
• Infill - 20%
• Wall thickness 0.8
• Wall line count 2
• Tree supports touching build plate

Materials Used:

• 5mm conductive tape
• M2.3 self tapping screws 8mm and 10mm
• 2x M6 and 4x M5 bolts.
• Superglue

Huge thanks to Wesk on the BitBuilt forums for releasing the original 3D scans - https://bitbuilt.net/forums/threads/ps-vita-hori-grip.6220/
