3D Printable Makerslide Actuator mount

thingiverse

This is a test to create a 3D printable actuator using Makerslide and .5in Acme rod. A part caught my attention where a washer was used as the metal contact point for the eccentric spacer, so I started designing this project using some parts I had on hand. I'm still unsure if it works because I don't have the bearings for the end bearing mounts, but I'm making progress. Currently, the printable sleeve for the nut is almost working, with a bit too much flex causing the v wheels to misalign on the rails when tightening. To test the design further, I plan to print with a stronger infill and reduce the low infill setting that's been used so far. If anyone has any suggestions or ideas, please let me know, and if this project works better, I'll make some parts with more than just a Makerslide mount. This actuator uses a 1/4" SAE for the internal 9/32" diameter to spin the eccentric spacer, while the other v wheel mounts are stationary, using only 5mm washers. The eccentric spacer side requires one 30mm M5 bolt, and the other two sides use 25mm M5 bolts, with one 5mm washer on each side of each v wheel. Printer Settings: Printer: Prusa i3 Rafts: No Supports: No Resolution: .2mm Infill: 20% Notes: I've been printing at 20% for fit testing purposes and will likely increase it.
