Accessories for Screw-in Rods

This is a remix of the good “Screw-in Rods for spool rack or other uses” created by mateocray

I needed a smaller one to hold a curtain between two walls and the possibility to extend it to exactly fit the walls without losing the original strenght, so:

- Scaled to 75%: now the diametrer is 18.5mm (about 0.73")
- Added a 40mm rod (1.57") 
- Added a 5mm bolt (0.2")
- Added a 10mm cap 
- Added a joint with a thread on one side and a simple cylinder on the other side that fits the hole in the original model (not used, but can be useful)

The 40mm male rod is used to connect two pipes with the female-screw. You need to insert two 5mm bolts and screw them tight to both sides of the pipes. Two TPU caps, one per side, give the grip to the wall.

Printed everything with PLA except the two caps in TPU.
Wall loops 6, 25% infill, use low speed because the pipes are pretty tall, no supports.

To fit the original size, scale to 1.333%
