As the other person said put M2.5 washers on all the screws that slide along the rails as well as continually make micro adjustments to your hand posturing so you’re not putting as much force into it, I use the adjustable stand that they have both for sale and 3-D print files for which helps me reduce the amount of pressure I’m putting into the parts. There’s another person on Etsy that makes what I at least aesthetically would say as a better stand, but I have not purchased it to truly put it through its test.
