EZM M328 component tester case

thingiverse

This is a case for another clone of the GM328 tester - in this case from EZM Electronics Studio. The board has just M328 as the model number, but the firmware says GM328. I wanted one that would expose the surface mount testing pads since I work with a lot of SMT stuff. Requires no fasteners, everything snaps together. The battery fits under the screen board in a compartment with a door. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: Yes Resolution: 0.2mm Infill: 30% Notes: I printed in ABS, extruder temp 245C (I think my hotend runs a little cooler than commanded) with a retrofitted heated bed (Kapton with PVA coat) at 110C. The battery door was a problem in ABS: the spring section would print as a gummy mess with the two sides fused together, even when slowed down to 8 seconds/layer. To address this I added the Tower of Distraction (a cylinder with the same height as the spring section) to be placed somewhere else on the bed, so the extruder would spend some time away from the spring section and the plastic would have a chance to cool. In PLA it prints without any need for the Tower. Nylons might or might not need it, haven't tested. Post-Printing For the ABS part I found it was helpful to use a hot air pencil/heat gun on the spring section to get better fusion between layers on the outside. This made it a lot more durable.
