Portable drill attachment remix for 24mm bearings and 1/4-20 bolt/nut

I made two tweaks increased bearing sleeves of the main frame to hold 24mm bearings more securely while keeping spring holder in original spot so that longer springs can still fit in modified knob traps to accept 1/4-20 bolt and nut. hardware I used - 200mm rods - 24mm LM8UU bearings - 3 inch 1/4-20 bolt and nut - two 11/32"x 1-27/32" springs
