Analogue Pocket MediumBoy Grip - Remixed from original by RobitGames
I shortened the grip on both sides to fit my hands better, now it feels more like classic GBA. I also deepened the back part by about 1mm+ so the grooves are a little more effective to grip on.
Variation 1 - added a hole to insert a thread for a wrist strap.
Variation 2 - MagSafe ring cutout. hole for thread, and hollow right grip to stash bluetooth transmitter.
For the insert, I used RX-1/4“-20x12.7 Brass Heat Set Insert, inserted using a heated soldering iron. The tight grip of the original grip itself makes the hand strap very secure and safe to use. If using thread inserts, I recommending using minimum 3mm of walls around the insert part. I solved that by adding a tons of bottom layers, or you can print solid at 100%.
