MMU V2 Autorewind Spoolholder for IKEA Samla BOX

thingiverse

Here's my spoolholder for autorewind, thanks for that great thing! https://www.thingiverse.com/thing:3252111, which fits into IKEA Samla boxes to store filament in dry and dust-free conditions. Included: * 3-Spool-Version for a spool width of 87mm (3 Spools in one IKEA SAMLA) * 4-Spool-Version for a spool width of 63mm (4 Spools in one IKEA SAMLA) * Spoolhub for this version for spools with an inner diameter of 53mm (eins3D Spools) To guide the filament out of the boxes, I'll use 4mm pneumatic couplers. (Design to be created, follows if I get the pneumatic coupler.) For usage without SAMLA, there's a FilamentGuide option included. What you need: * 4x M3 min14mm screws with nuts * 2x M3 countersunk bolts min 6mm with nuts * 2x M3 countersunk bolts min 6mm without nuts (Filamentguide option) * 2x ball bearings 608 from the original Prusa MMU V2 spoolholder * An autorewind spoolhub (https://www.thingiverse.com/thing:3252111) Included are spoolhubs for a spool inner diameter of 53mm (in use eins3D filament spools). Other diameters can be created with this thing https://www.thingiverse.com/thing:3252111, or I can create it for you if you tell me the diameter. You need special axes for this spoolholder, but they are included too. Do not use the original axes! For easier tightening of the screws of the frame, there are little holes for the Allen key. UPDATE 02.01.2019 Added a custom 78mm width frame (without hub, please use the https://www.thingiverse.com/thing:3252111) UPDATE 05.02.2019 Added PTFE tube coupler and pictures of my boxes For one coupler, you need three 4x10 DIN7991 countersunk bolts with M4 DIN934 nuts and a pneumatic coupler of your choice.
