Doubled brackets for improved MMU spoolholder

prusaprinters

<p>I liked the idea of @AndreasO to stack the spoolholders of MMU units to save some space.<br/> I took his brackets and designed doubled brackets to interconnect the 'spooltowers' for more stability.<br/> There are three different designs:</p> <ul> <li>UpUp with two upper brackets</li> <li>LowLow with two lower brackets</li> <li>UpLow with a lower and upper bracket</li> </ul> <p><strong>For MMU1 you need:</strong></p> <ul> <li>2 x spoolholder_LowLow</li> <li>2 x spoolholder_UpUp</li> <li>[4 x spoolholderlower]*</li> <li>[4 x spoolholderupper]*</li> <li>[2 x spoolholderback]*</li> <li>[4 x spoolholderstand]*</li> </ul> <p><em>* From AndreasOs original design <a href="https://www.prusaprinters.org/prints/25183">https://www.prusaprinters.org/prints/25183</a></em></p> <p><strong>For MMU2 you need :</strong></p> <ul> <li>2 x spoolholder_LowLow</li> <li>2 x spoolholder_UpLow</li> <li>[6 x spoolholderlower]*</li> <li>[6 x spoolholderupper]*</li> <li>[3 x spoolholderback]*</li> <li>[6 x spoolholderstand]*</li> </ul> <p><em>* From AndreasOs original design <a href="https://www.prusaprinters.org/prints/25183">https://www.prusaprinters.org/prints/25183</a></em></p> <h3>Print instructions</h3><p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> i3 MK3s MMU2s</p> <p><strong>Rafts:</strong> Doesn't Matter</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0,2 mm</p> <p><strong>Infill:</strong> 20%</p> <p><strong>Notes:</strong></p> <p>I recommend a brim for the Spoolholder_LowLow.stl, Spoolholder_UpUp.stl, Spoolholder_UpLow.stl</p> <p>For detailed Instructions see <a href="https://www.prusaprinters.org/prints/25183">https://www.prusaprinters.org/prints/25183</a></p>
