Prusa Bear Y-Rod Holder no zipties (only screws)

prusaprinters

<p>Hi!</p> <p>This thing is the Y-axis rod holder for Prusa Bear upgrade but with no zip-ties.</p> <p>The rod is held in place with 2 pcs. M3 x 14 screws.</p> <p>I printed in Polycarbonate with 4 perimeters, 8 top and bottom layers and 30% infill.</p> <p>Althought the clamp is quite thin on the top (1mm), in order to secure clearance for the printing bed, I used Polycarbonate and the part is very strong. I paid attention not to have sharp corners on the clamp as there can accumulate a lot of stress (that can induce cracks) when clamping the rod in place. Also, there is a tolerance of 0,2mm between the main body and the clamp to ensure that the pressure from the screws is discharged mainly on the top of the rod, where it's needed. Other advantage of this clamp is that it's stronger than one ziptie , having the cross-section 3 times bigger (at it's thinnest spot) and offers reliability as I will stay in place very secure, with no risk of getting loose because of heat or stress. Please let me know what you think and what should be improved ! Thank you.</p> <p><a href="https://www.facebook.com/groups/prusabearupgrade/permalink/1427650260728613/">https://www.facebook.com/groups/prusabearupgrade/permalink/1427650260728613/</a></p> <p>I guess PETG should also work but please do with more infill, even 100% just for the clamp as it is quite thin on the top.</p> <h3>Print instructions</h3><p>Category: 3D Printer Parts</p>
