Description
Test probes for multimeters can be expensive and most are not ideal to measure tiny SMD parts. This is why I designed these grips that work with test probes commonly used in in-circuit-testing.
The design basically consists of two 3D printed parts that interlock using some kind of bayonet connection.
Additional you need the electrical components, which are:
PTR H 1025 L - precision test tip sleeve (for soldering connection)
PTR 1025/E-BST-1.5N-AU-0.62 - precision test tip (these have a pointy end of 0,62mm but there are other test tips available that fit the sleeve)
..plus some basic stuff, like cables and connectors. I used Hirschmann LAS S WS 4mm connectors and Stäubli FLEXI-E 0,5 mm² wires, which is very flexible.
I printed it with a regular 0.4 mm nozzle with BambuLab PLA Basic/Matte and it worked fine. Hope the tolerances are okay for the connection between the two parts. Some force was needed but I could push and twist the 3D-printed-tip inside the grip without using tools. You have to make sure there are no leftovers from support-structures sticking to the tip, though.
This is an updated version. The old one needed tiny screws to keep the parts together, but this version works without screws.
Important: Since these tips will be used with Electricity - please don't use them in combination with hazardous Voltages! Don't electrocute yourself!
