A simple and strong rack for pasteur pipettes. This model requires M3 DIN 934 countersunk screws. This is designed to hold not used or clean pipettes in the back 3 rows, and currently used 5 pipettes on the front row. You can place bottles on the bottom plate. The front row pipettes are designed to be used with bottles. The maximum bottle diameter is assumed to be 40mm. Print notes: For Mid, Top: Print without supports or add support blockers to screw holes. Enable For Bot: Print with supports. For Back: You don't need support. Make sure the countersunk side is at the top.

3 x M3 DIN 934 countersunk screws are required per horizontal part, so 9 of them in total. Lengths do not matter as long as they are not short. The holes are extended so that screws can be longer than required.

I did not print this version. The previous version had the same mechanical connections, but the thicknesses and some aesthetics are different. So this should work too. P.S.: I have tried to add some jazz by giving it not-required holes. I know it does not look good, but it is better than nothing.
