Robust PCB Holder 20x20 Only + 3/4in spacer

thingiverse

Update: Integrated angled spacers to enhance the fit between 3/4in square tubes and 20mm slots, simply print two and insert them with the plastic facing the opposite side of the bolt that tightens the vertical arms. This adjustment has significantly improved the structure's stability. The original design employed a combination of 20x20 square tubes and 20x30 square tubes; however, I only had access to 3/4in stock. The revised Side Holder features minor material reductions to minimize print time and filament usage, given that my available tube is 2mm thick. Consequently, the included caps did not fit properly. An alternative cap has been designed to fit snugly into the tube I have on hand.
