I have created a teeter totter educational aid. The fulcrum point is adjustable. This object can be used to balance masses and demonstrate to students the concept of a moment. M = F * D. As the distance increases, the force needed to create the same moment decreases proportionally. This is an educational aid for elementary age students. I created all of these objects using FreeCAD. It is 47 Grams of material. This would cost approximately $0.94 USD. Assuming PLA is the material used and the price is $20 USD per kg. A compareable object cost is $3.29. This is more than a 60% reducation in cost. I have attached a link to the comparable object:  https://www.eaieducation.com/Product/504030/MiniMathBalancewithWeights.aspx?utmsource=GoogleShopping&utmmedium=GoogleShopping&utmcampaign=GoogleShopping&gclid=EAIaIQobChMIobTNoYK15QIVAtvACh33hQFNEAQYASABEgJ0GDBwE&utmsource=GoogleShopping&utmmedium=GoogleShopping&utmcampaign=GoogleShopping&gclid=EAIaIQobChMIobTNoYK15QIVAtvACh33hQFNEAQYASABEgJ0GDBwE
