Lego Technic Pneumatic Pump Rig

thingiverse

The D2028B air compressor module can be easily integrated into the Lego Technic system by creating *this rig* which enhances play by eliminating the need for manual pneumatic pumping. In addition to the printed parts, also required: * 1x D2028B pump module * 2x 3M 40mm Allen screws * 2x 3M 5x5 bronze inserts * 4x 11-hole Lego lift arms To ensure a seamless integration with the rest of the Lego system, I opted to use original Lego lift arms and affix them to the printed holder with glue. Alternatively, one could print smaller holes and screw directly into the plastic instead of using brass inserts, but this approach may weaken the joint's durability.
