Its a replacement guard for the chain on a bike

thingiverse

Replacing traditional chain guards on bikes can be tricky, but with modern 3D printing capabilities, you're able to fabricate replacements with precision and speed. My bike's old chain guard had been showing signs of wear and tear for a while, so I took matters into my own hands - quite literally, by getting creative with DIY printing techniques. However, one obstacle stood between me and successfully producing this guard: my humble printer just wasn't up to the task. With careful planning, we can slice down large 3D designs into more manageable pieces, making them accessible even for smaller print beds. By cutting these designs in half (or perhaps even further), you might be able to pull it off without breaking the bank or upgrading your equipment. To give those with constrained space a head start, I've attached some sliced versions that are perfectly suited for smaller beds - no excuses left. I managed to crank out this baby using the venerable TF1 printer, reminiscent of that iconic early Pursa prototype everyone loves to talk about. It printed at a scorching 235 degrees Celsius on the finest quality ABS filament around. While preheating the glass covered print bed reached temperatures as high as 110 degrees Celsius. This job used the low settings available through RepeaterHost and my go-to slicing tool for precision and smoothness every time - RepeiterHost Slicer indeed delivered when it counted the most.
