Runner weight loading pin

Made a weight loading pin for weights with 25mm centre hole for use at home and also at my climbing gym. 

Print the model twice, insert the aluminium/steel rods and then wrap the sling/runner around the rods as shown in the second picture. Before pushing the second printed half add a small drop of glue to the overlapping section to secure everything.

Additional items you need:

• 6cm long 8mm aluminium or steel rod x2
• 60cm long 18 or 20mm wide dyneema sling/runner

NOTE: To make sure the model can withstand the weight make sure to print at a high infill percentage with a high wall count. 

I printed mine with 4 walls, 4 top and bottom layers and 70% infill wich seems to work great but use it at your own risk!
