GL45 Inlet with 1-5 Ports

thingiverse

These 3D objects are inlets for typical GL45 laboratory bottle caps. They can be used as lids for the typical (cheap) GL45 screwcaps with a cut-out (https://www.thingiverse.com/thing:4614641). While these inlets alone cost a fortune, they are relately simple 3D objects that you can print for way less. We use them as adapters for feeding bottles in a bioreactor set up, were we attach tubing to the ports reaching to the bottom of the bottle. You may have to carefully choose orientation and printing technique, since the holes within the ports are only 2 mm in diameter. I print them with an SLA printer with the tubing holes in vertical orientation. Have Fun
