Trolley cart conversion kit for BASIL MIK bicycle crate

Customize your detachable BASIL bicycle crate (MIK) into a trolley cart with a telescopic handle!

Example product: EAN: 8715019211478 

With this,

• If you use supermarket self-checkout, you won't have to transfer your purchase to another bag. Just use your bicycle crate instead of the trolley provided by the supermarket.
• At the supermarket, you can avoid buying more than you can carry on your bike. You fill your bicycle crate, that's all you buy.

Design Notes:

1. The telescopic handle can lock once extended, so you can also use it to push the crate.
2. Manufacturer recommended max. load of a BASIL crate is 10 kg. This design - while not precisely calculated - is not meant for heavier loads.
3. The castor wheel base plate is designed for 50 mm castor wheels designed with M4 screws/bolts.

Printing:

• Print the tubes slower.
• Print the handgrip with 60% Gyroid infill (otherwise it will break)

Assembly:

1. Start with assembling the telescope, inner tube in the middle tube, then that assembly in the outer tube.. Pay attention to the grooves. When sliding stops, rotate one 90 degrees against the other and then slide fully in. The telescope is designed to lock in place when rotated by 90 degrees.
2. Fix the telescope on the base plate by rotating the threads. Optionally, use locking pins.
3. Fix the handgrip at the other end of the inner tube. Optionally, use locking pins.
4. Mount the base plate and holder plate onto the BASIL crate as shown in the photos. Optionally, use the locking pins. Here, I recommend using the pins because they will prevent damage to any delicate stuff in the crate.
