The gas springs on the screen printing rig are rather weak and keep dropping the screen arms. I did a little research and found what I believe are viable replacements. I am not familliar with how the makerspace does this sort of thing though.
I used one of the gantry scales and measured 22-24lbs on one of the stronger arms. Based on that, probably a 30lbs replacement would work. The springs are 7.5 inches (center to center) extended, and just over 5.25 compressed. I am pretty sure they have 10mm (3/8") ball sockets, but I did not actually measure that.
To back that up, the existing springs are labeled “avm NPDSE200A80PS30”, where I believe the 200 represents the overall length in millimeters and the PS30 represents the force in pounds, but I cannot seem to find any specs for the original springs.
Based on the above, I believe the following would work for replacements:

2 for $30, free shipping, maybe buy one set, see if they work, and if so, buy another set as well.
The details on the spec can be found here:
30lbs, 7.5" length extended, 5.25" compressed, 10mm ball socket.
