P3steel x axis carriages and belt tensioner

thingiverse

I reworked an existing design based on the Prusa to fit my P3steel printer. I noticed that some current designs for the P3steel were not accurate, particularly with the lead screw circle and 8 mm smooth rod circle not being co-linear in several of them. To improve the belt tensioner piece, I reduced its gap to snugly hold two flange bearings (F623ZZ). Printing these parts requires no support, and their dimensions should be fairly tight to prevent excess play. If some holes were slightly too small, a Drimel can be used to adjust and resize them. Before printing, it's essential to check the center distance between the smooth rod and lead screw on your Prusa or P3steel printer, as shown in one of the images. This distance should be 17 mm. The parts are printed from Innofil Pro1 PLA filament. While I used PLA for these prints, it's recommended to print all parts in either ABS or PETG for increased tensile strength. Update: On October 25th, 2018, my previous PLA idler broke due to fatigue, and I highly recommend printing all parts in PETG. The lead screw used is a Tr8x8 with a brass nut that can be easily found on eBay or Aliexpress at the following link: https://www.aliexpress.com/item/RepRap-3D-Printer-THSL-300-8D-Lead-Screw-Dia-8MM-Thread-8mm-Length-300mm-with-Copper/1544741545.html?shortkey=6by6ZnAn&addresstype=600. I welcome any feedback from users.
